The biggest news coming out of evo was the announcement of Ultra Street Fighter IV. They announced 5 new characters, and only revealed 4 (Rolento, Elena, Hugo, Poison). We know the four that are announced already are ports from SFxTekken, the fifth one is a character "never seen in Street Fighter before" (So it's not Alex, quit saying that). So who could the fifth person be? Here are some of my guesses.
Asura- Based on how lazy Capcom appears in this, bringing Asura to Street Fighter is another easy move for them. They could just use the work from the Asura's Wrath dlc to do it. I would love this because it would mean that Asura's Wrath 2 is coming. Why else would you just randomly throw Asura in there? (Aside from it being easy, of course).
Box Art Mega Man- Never seen in SF before? Check. (I don't think SFxT counts) Port. Check. Other reasons would be to hype Mega Man returning, and to be stupid.
Now for the above 2, Ono deconfirmed them on twitter. However, Ono loves to troll, so take that with a grain of salt. With those two ruled out, let's get a bit weirder.
A Darkstalker- As much as I love Darkstalkers, the series seems to be dead. Sales of Ressurection were a disappointment, and they've been teasing Darkstalkers for so long, it seems that ship has sailed. However, if they decided to bring it back, what better way to announce it than a new DS character. I would love this so much. As for the character itself, easy money would be Demitri or Morrigan. Imagine Midnight Bliss on the Street Fighter folks, it's been done.
Haggar- This has been speculated across chats and twitter, it would close the loop (He's the only hero from Final Fight not in a SF game so far). And since you're adding two Final Fight villains, why not?
Scorpion- Worked for Injustice. Even though I would find this hilarious, no chance. Moving on.
Somebody from SNK: All evidence out there so far suggests this being the right answer. Why? First, King of Fighters is probably bigger than it's been in a long time, XIII sold really well, and the huge showing at Evo 2012 (Not to mention this year) only exposed that to more people. Based on steam data, KoF13 is probably coming to Steam. King of Fighters celebrates its 20th anniversary next year, and what would be a better tribute from Capcom than putting an SNK character in there? Better yet, what better way to promote a new Capcom vs SNK game? This week they're putting CVS2 out on PSN, kinda out of the blue don't you think? It would be a safer bet for Capcom's new fighting game than Darkstalkers, and what better fighting game to kick off the next generations of consoles. Don't say Killer Instinct.
So, after all that speculation, I predict that the 5th character will be from SNK. Probably one of the main people (Kyo, Mai, Iori). It makes the most sense. Unfortunately, we're dealing with Capcom here. So if it ended up being a Resident Evil or other crazy character (Scorpion!), I wouldn't be surprised. But with all of the stuff mentioned above, someone from SNK seems like a pretty safe bet.
Am I crazy? Or is it going to be one of the others I mentioned above. Someone else maybe? What do you all think?
