yes I KNOW that Q isn't from Alpha. All i'm doing is guessing what Capcom is going to be doing with the info that we have right now. They showed that Charlie is going to be in the game, where did Charlie come from? The Alpha series. If Capcom sticks to this theme, which they did when they added in the majority of the Street Fighter 3 cast into Street Fighter 4, we might be seeing characters like Karin being added in the roster. And if Q is as popular as people say he is then why wasn't he added into SF4 along side Duddly or Makoto? Would have made sense.
I don't think there's enough out there to even see a pattern of who's likely and who's not. Ryu and Chun Li are super popular mainstays. Initially Chun Li wasn't in SF3 until 3rd strike, lots of controversy in the past over omitting so much of the cast, so SF4 comes around and brings back several SFII and Alpha favorites-- now my point is, I feel from here on out at the very least Ryu and Chun Li will always be around. Now that's out of the way, them adding Charlie was awesome, but it's not enough of a clue to say that we're probably getting more alpha characters.
The fact is that there's so little in terms of info for SFV, and already people got confused with the mistranslation of the Ken Bogard thing thinking we were getting 16 characters. We still might, we might not, but the issue is, he didn't even have a specific idea of the roster size.
There's been rumours and speculation that due to the Denjin Hadouken, Chun Li's stance, and the showcased stage that it may take place after or lead up to SF3, but again, that's speculation once more. On the flip side, for the Alpha direction, some people feel that the Capcom UK history video featuring Rose might be a hint that she's coming up next on the revelation circuit.
At the end of the day we've got just a little bit of info and may get some more with upcoming con appearances or something. They've probably finalized or pre-finalized that cast in writing, but since they're only around 20% done, we're not going to get more information (at least huge stuff) for a bit.
Lastly, the most important thing is that above all else, for this entry to succeed, it needs to give a certain amount of focus to bringing on an element that will bring joy, curiosity, a hungering for Udon noodles, adrenaline rushes and trench coats....Q. Q needs to be included. For with his inclusion, as it was foretold in the back of a soggy newspaper in a Hell's Kitchen Alley (next to Lou's Fine Meats) 15 years ago, it would move the world one step closer to world peace.....it's true.
....TOTALLY TRUE!
