This is from the official Street Fighter twitter.

edit: seemed they erased tweet. Here is what the tweet said: StreetFighter: @WhyDoPeopleThink #SFXTK's roster is finalized?! It's not!

But why was it erased then? Maybe it is finalized.

Can't tell till Capcom does an official press release or they release the game.

Just put ORO in the game already. I wanna be hitting motherfuckers with that trash again.

Q son, Q!!!!!!?!!!?!!?!!!!

There was a roster leak months ago that dropped incredibly specific details about Boxart Megaman, which of course seemed ridiculous at the time. I can't remember if M. Bison or Akuma were on the SF side of that list, but I did remember seeing Elena, which had be very excited.
 
p.s. I can't find the source of the post this guy is referencing, but here is someone quoting the very same leak back in November:

On Street Fighter's side, there is:
1.Ryu, 2.Ken, 3.Guile, 4.Abel, 5.Chun, 6.Cammy, 7.Sagat, 8.Dhalsim, 9.Zangief, 10.Rolento, 11.Ibuki, 12.Hugo,
13.Poison, 14.Blanka, 15.Vega, 16.Balrog, 17.Bison, 18.Dudley, 19.Juri, 20.Elena, 21.Cody, 22.Guy, 23.Rufus, 24.Akuma

Tekken's side:
1.Kazuya, 2.Nina, 3.King, 4.Marduk, 5.Bob, 6.Julia, 7.Hwoarang, 8.Steve, 9.Yoshimitsu, 10.Raven, 11.Kuma,
12.Heihachi, 13.Lili, 14.Jin, 15.Jack, 16.Bryan, 17.Law, 18.Paul, 19.Asuka, 20.Christie, 21.Leo, 22.Lars, 23.Alisa, 24.Ling, 25.humanoid-Ogre

Also there are two special characters: PacMan, who is controlling and riding ontop of a Mokujin (like Tron Bonne). And Megaman, but not what you would think. It's the crappy Megaman with handgun that was on the coverboxart of the USA MM1 game! He was going to be in that upcoming MegaMan Universe game, but unfortunately, it got cancelled.

Elena or gtfo

either they want to surprise us with 4 or (less likely) 8 more fighters in a week, or they will be DLC and they want to talk about that post-release.

if they go with DLC I hope the leaked pricelist is right and it's 5bucks for 4 fighters, because that sounds pretty reasonable.

Yun and Yang! :D

MIKE HAGGAR CONFIRMED!

really? where? lol

Dat DLC.

Eddy Gordo please.

apparently there will be a day 1 patch and maybe(a big maybe) it will put in more characters.

It's criminal to not put Dudley in this game, I hope he makes the cut. He's a fucking combo machine, he'll be crazy in this.

If I had to take a guess I'd say that the roster is complete, but they probably have like eight DLC characters ready to come out, so that may be why they deleted the tweet. If they left it up people would think there would be more characters coming on the initial release when they'll probably be DLC.

i was actually shocked to find out E Honda wasn't part of the roster...when i saw Mike Ross use a different character i was like WAHHHHH!?
