There is no question that all old school SF players are looking forward to the release of this amazing collection. There are some new gameplay videos that have been posted by a few sources. Maximillian Dood and PlayStation have both posted excellent gameplay videos for the games.
So far it seems like the only game that is looking off in terms of speed is Super Turbo. Being that this is my personal favorite game in the series, I hope they lower the speed a bit, but even if the game comes out at that hyper fast speed, I will definitely play it.
