I kinda am looking into the Revolution. it's gonna have a totally different type of game play... I'm looking forward to that, plus it'll be cheap, so it might not have the top CPU or top graphics, but the game play will be unique.
As for the other two, I still believe that PS3 will take the cake, even with Xbox360 having the early lead.
Competition= good because we benefit the most from two companies duking it out for better technology. Look at ATI and Nvidia, they're duking it out and we're getting games with better, smoother graphics that would have been unimaginable 10 years ago. We are getting graphics processors that make games look better than many computer graphic scenes in older movies.
