Hopefully this is just the first of many, or at least a few, that will release its prior games for the new console and even if we are still missing many; Final Fantay, Street Fighter, Mega Man, Breath Of Fire, Contra, Gradius, Blades of Steel, etc. the list is longer than I have room for here, we can just hope that more will follow in Sega's footsteps and eventually decide to support Revolution, and if so Nintendo's coming console will sport the top games from first ~15 years of the industry's life (!).
Playstation 2 obliterated the competition with a similar sales argument and then it was just the older Playstation games that was supported. Here we have, best case scenario, the entire industry backing up the coming console.
