MLB 2K10. See, you're going to need as much practice as you possibly get in order to pitch a perfect no-hitter once the game's released, effectively netting yourself a cool million bucks.
However, though the demo is currently available on Xbox Live, PS3 owners won't have access to it until March 4 -- two days after the full game is released. By that time, the 360-owning populace will have had over a week to turn their pitching arms into Randy Johnson-esque baseball cannons. Depending on how you look at it, that's either a huge handicap, or the makings of a fantastic underdog story.
