DC on Xbox rumour is false, at least until Tokyo Game Show.
DC still has about 100 games this year, so at 99 bucks, it's a definite steal. Even if no new games came out, there's so many great games for DC that you'd be dumb not to get it. Games like Jet Grind Radio, Grandia II, Skies of Arcadia, Virtua Tennis, NFL2K1, Phantasy Star Online, Test Drive LeMan, MSR, Sega GT, Soul Calibur, NBA2K1, Shenmue, list goes on and on.
Tons of new games too like Shenmue II, PSO2 (maybe), Gundam, 18-Wheeler American Trucker, Virtua Tennis 2, NBA2K2 and NFL2K2, World Series Baseball 2K2, NHL2K2, Flogian Bros, tons of other stuff I can't remember.
I actually just bought my DC like a month ago (sucks, had to pay 149) but its a darn good system with tons of great games. It's a next-gen system (will a lot of life left in it) priced like a today's system. PSOne? or DC...hmmm?
