It seems to be a question they are getting asked alot.
I think what they were trying to do with HDremix was also get people playing SF games just before sf4 came out and they dont really want to do it again while sf4 is so big…maybe when sf4 dies down a little?
The Third Strike sprites are a lot cleaner than Super Turbo, so the MvC2 approach might not be a bad idea. As long as the netcode is good, I think that would be great.
I bet they would release the rest of the Alpha series for the psn store first. more money that way. Plus they really dont see the rush with the current excitement of another said Street Fighter game…
