I wouldn’t know! It’d be up to Enterplay to do so, and it would take them some time to come up with it. They just did series 2, so I don’t think they’d want to make another line so soon.
Clear Funko SDCC Exclusives and Wave 8 Blind Bag Codes

Funko has listed off some hints for their SDCC exclusives, which reference ponies. Feel free to check it out yourself, or be assured that Derpy is getting a clear variant. The hints aim at there being a clear Rainbow Dash vairant, too.
SDCC exclusives can be pre-ordered by people attending the event. You can also pick them up there. Info is on the link above. Info from 3377345 from the MLP Arena.
Breyer600 of the Arena got an entire case of wave 8 blind bags and shared the codes. Unlike before, the codes are two letters, with the first being A and the second corresponding to the pony inside. The codes are embossed on the bottom of the bag below the MLP URL and can be read from the front.
A = 01 Applejack
B = 02 Big Macintosh
C = 03 Royal Riff
D = 04 Mosely Orange
E = 05 Gilda
F = 06 Flam
G = 07 Flim Skim
H = 08 Fluttershy
I = 09 Skywishes
K = 10 Granny Smith
L = 11 Princess Cadence
M = 12 Golden Harvest
N = 13 Flower Wishes
O = 14 Pinkie Pie
P = 15 Sassaflash
R = 16 Comet Tail
S = 17 Rainbow Dash
T = 18 Sunny Rays
U = 19 Gardinia Glow
V = 20 Lemon Hearts
W = 21 Rarity
X = 22 Ribbon Wishes
Y = 23 Lotus Blossom
Z = 24 Twilight Sparkle
The dolls will probably be unveiled via SDCC, though I wouldn’t be surprised if someone spots them on Taobao beforehand.
Gens are based on toy lines, marketing and art. One of the biggest ways to tell this is by what else is in stores in the time and the logo. EqG will be sold along with G4. We know that there’s a whole major line launching in the fall, along with the TRU Collector’s line for the summer.
Logos change as the gen is rebooted/restarted, which also shows the change in art and marketing.
G3 logo

G 3.5 logo. Note that it’s similar, but more stylized.

G4 logo. Quite similar to G3.5, huh?
EqG Logo. It’s the G4 logo with the “Equestria Girls” heart-shaped horseshoe tacked on.

EqG is very clearly part of G4: We even see the “normal” FiM ponies in the beginning (and presumably the end) of the movie! Each gen reboot brings ponies to new lands and new worlds. G1 was Dream Valley in Ponyland, G2 was Friendship Gardens, G3 was Ponyville and G4 was Equestria.
We can think of EqG a lot like how MLP Tales was handled. Tales was a spin-off of G1. They were still ponies, and they still lived in Ponyland, but they lived in a small town, went to school, were interested in boys and did normal late 80’s girl stuff.

The art itself was pretty much exactly the same as MLP and Friends, but Tales ponies walked on their hind legs sometimes, drove cars and worked jobs. They had a clear class system, varying governments and reproduced by natural means (G1 ponies reproduced via a magic mirror, as explained in a comic).
You could imagine how Internet communities would react over MLPT if they existed back then. Ponies going to school? Ponies fawning over boys? Ponies acting like humans? It’s the same things that people are saying about EqG today.
Tales came out in 92, which was also the last year of G1. G2 started in 97 and ran until 99 in America, though it was out until 2002 overseas. G3 started in 2003 and ran up until 2010 when G4 came out. Tales was just a way to market ponies to older kids.
I won’t be making a seperate blog for it, as it’s still technically G4. The dolls are also being bundled with pony toys, which people here will be interested in.
I tag all of my posts based on what type of toy it is (blind bag, fashion style) and what character its concerning (Twilight, Rainbow Dash). I’ll be tagging all EqG posts as Equestria Girls, so you can always grab the extension Tumblr Savior! Google it and you’ll find it for your browser.
Basically what it does is look at all of your posts on your dashboard. It takes what you have on your blacklist, and if a post contains one of the blacklisted words or phrases, it “hides” the post, saying “Blog has a post that contains X.” You can click a link to expand the post if you still want to see it, but it will hide EqG from your dash.
Tumblr Savior, though, doesn’t work when you visit the blog itself. So you’d still be seeing EqG posts if you visit mlpg4merch.tumblr.com.
She said Sunset Shimmer wouldn’t be in s4; she’s in the stand-alone movie instead. Most people read what she said too quickly to realize the exceptions she left in.
The DVD cover/movie poster has her with wings!

Perhaps she gets her human wings at the end of the film?
The merch can easily have wings or not for the main characters. I think it would lean to not having wings, as it would be easier to produce, make clothes for and package. But they can easily put in wings, too. Monster High puts tons of stuff on their dolls without issue. We still have 0 idea what the toys will look like.
The NYT piece said it would be release on DVD in the US and in other countries, so most likely yes. Which countries, I can’t tell you.
Equestria Girls DVD, BD for Preorder
Equestria Girls, the spin off movie of FiM, is reaching select theaters this summer before it hits home media. If you’d rather pick it up as a disk, Amazon has them up for Blu-Ray ($17.48) and DVD ($11.89).
They’re both listed as “August,” but the New York Times article on the movie lists home media as releasing as this time. The Amazon listings also say the media is 72 minutes long, the length of the Equestria Girls movie. The Blu-ray also has two discs, which could mean it’s a DVD/BD combo pack. The DVD is region 1 formatted. Both are up for preorder and will be out August 6.
The NYT article notes that EqG will also have toys, apparel, “publishing,” accessories, an interactive site, YouTube content and a partnership with Stardoll.com. The movie itself will premiere at the Los Angeles Film Festival in June and soon come out to theaters. It will air on The Hub in the fall in case you’d rather not go to the movies or pick up the home release.
Alicorn Twilight and Spike to Join Build-A-Bear Line

Equestria Daily reports that Build-A-Bear’s image archives now have product images for alicorn Twilight and Spike.

Twilight looks to be about the same size as Rainbow Dash and Pinkie Pie and can be expected to be a similar price. She has shiny wings and horn, much like the fabric used on Rainbow’s wings, along with Luna/Cadance-shaped wings like she has in the show.
The image of Spike is much smaller; he might be a “mini furry friend,” a smaller plush animal generally under $10. He could also be sized differently and be a full-sized plush like everyone else, which would lead him to not be in scale but be much more cuddleable.
BABW staff have reported that these would be the next toys, with these images confirming it. Release dates, prices, accessories and other info is currently unknown.
