Well.. I dont know how that works. Because X10 is going to be so new and different, I dont know if games will be compatable.. Although, logicaly thinking they have to be. Anyways though.. I THINK forever... Well not really, but, like.. If things have to be backwards compatable, X9 games will work on X10. Unless Vista changes EVERYTHING..
Im not sure if im explaing this right.. What im trying to say is that, X7-8 games can work with X9C. So I see no reason why X9C games wont work with X10. So if they keep making X9C games, they should work untill maybe X11 comes out.
But im just guessing.. Because I mean like. Vista could be totally different, and X10 too new to work with anything else. Thus.. nothing else would work.. I mean they are making us get new cards for a reason. But im just not sure on this..
