Gradius in LittleBigPlanet: Is this PS3's breakout game?

After months of watching from the sidelines, Sony seems to have come out with a winner in the console wars with this LittleBigPlanet. Aside from amazingly detailed gameplay, you can program your own minigames into the game like this odd mechano-Gradius that looks like a puppet show.

What would it take to get me to buy a PS3? More games like this and some sort of franchise like GoW that is compelling and deep enough to warrant spending $500 on the console and another few hundred on games. What say you all?
