I've seen loads of those G25's on ebay now, all saying they work with PC, PS2 and PS3

hmm. Such a shame that the one wheel won't work with 360 as well 'cos I want the wheel mainly for GT5 Prologue as I think that game will really suit the wheel more than anything else, but I have more driving games in total on the 360 (Forza 2, PGR4, DiRT...)
