I think it has to be Blu-Ray. I've met the most random people talking about the PS3 they just bought - people who have never owned a system before, and ones who really have no intention of playing games, really.
Quick comments on above posts:
I agree with the idea that GT5P is NOT a top 5 game. It's not even the full game and has an 81 metacritic average. The only one that's a surefire top 5 game there is MGS4, and that may be top 5 critically but not commercially. Gears will sell more, as will Madden, GHIII, SSB Brawl and likely some others, like possibly Fable 2, that is expected to do well but comes out as a game way beyond what we expect (just as an example - who knows with Fable?).
I don't think it's possible for a PS3-exclusive game to be a top 5 seller this year yet.
Can't we all just get along and play our games in peace?
