I'll be getting a Revolution.
When it comes to original, creative games, you just can't go past Nintendo. I find that the games for PS / XBox are too much 'generic shooter/fighter/driving game' or 'Madden golf/tennis/football/soccer' titles.
I only buy a couple of games a year, and only one console, so I prefer the console with the very best games. For me, Nintendo with Mario/Zelda/Metroid/Wario is a nearly impossible system to beat. Nintendo has the greatest collection of 'clever/creative' games for it.
I think that in the upcoming generation of systems, the Revolution will do badly again, at least in the US / Australia. Nintendo just seems to have a bad image amongst gamers as a low-power 'kiddies' system, which I think will continue. Sony and Microsoft's BS marketing campaign of pre-rendered screenshots and laughable 'triangle counts' will again rule.
