Street Fighter Alpha imo was the best in the series but Capcom seems to be continously remaking and doing DLC for the Street Fighter 4 series. I am not a huge fan of the SF4 series but I guess it's still fun. Are we ever gonna see Alpha get revived or is capcom totally headed in the wrong direction with this series among others(Megaman, Resident Evil)?
They are pretty much done with the Alpha series.
As they have ultimately milked it as much as they can.
Even released that anthology collection on PS2 and the revised edition on PSP of Alpha 3.
Anyways, SFIV will get some lovins for the next few months. I think sometime in between 2 years from now there will be an announcement for SFV for next gen systems and PC.
