Not a fan of any of these rumors, to be honest. Ultras were already way un-balanced amongst the cast as is, and now there's possibly two Ultras per character? Without some sort of Super Art or selection system for this, I'm afraid.
Also, Alpha characters are unbearably lame. It's bad enough that the console version got nothing but these rejects, but now they want to throw in more? It's nice to see some 3S characters in there, but I think they could have done better in that regard (Ibuki is the weak link).
Speaking as a huge Zangief fan, he doesn't need an air-throw and an air-activated, most-likely-to-be-instant-Ultra-air-throw sounds like a nightmare for everyone.
I was a big nay-sayer of SF4 before I got my hands beta versions and it all turned out great.. which is why I get very concerned when I hear things like the new version "plays nothing like SF4."
Here's hoping they're just rumors
