There's a big difference between the 280 dollars that the 360 bundle with Blue Dragon cost in Japan (rough estimate based on exchange rates, obviously), and the 600 dollars for a PS3. I might have bought my Wii more or less just to play Twilight Princess, but it was only a 250 dollar console, and I already knew there was stuff I would want in the future (Super Mario Galaxy, Super Smash Brothers Brawl). LittleBigPlanet looks fantastic, but unless a whole bunch of the exclusive games for the PS3 turn out to be great as well (Lair, Warhawk, Heavenly Sword, etc.), I'm not coughing up 600 just to play it. Although hopefully by 2008 (when LBP is supposed to be finished), it won't cost 600 dollars anymore.
Also, did you guys here Warhawk is multiplayer only now? How wacked is that shit?
