First off, know that I'm a fan of Darkstalkers and that Street Fighter Alpha 2 is my favorite game in the SF series. With that out of the way: NO!
The Alpha series are fast and aggressive fighters and we know that Ono likes slow, sloppy fighters with stupid strong comeback mechanics. I don't expect their up to the task for either game.
Sadly, Capcom has learned nothing from the boom and crash of the genre in the 90s. I honestly feel they're business practices will hurt the fighting game genre in the long run. They keep reiterating and forcing fans to buy new disc-based titles and eventually the fans will be fed up, stop buying and Capcom will abandon the genre again, taking half of the community along with it. Fans of smaller fighters will be fine but the community as a whole will take a big hit.
