Don't get plasma for games. They will burn in. If you want the best TV for games or anything else, go for an LCD Flat panel TV. They don't burn in, they are much lighter than plasmas, and last a lot longer. The newest samsung model is awesome. 1080p, 15000:1 contrast ratio and no banding (if you haven't heard of banding, it's where different parts of screen are at different brightness levels. Some LCD TV's have this problem. The new samsung model does not). It's got 3 HDMI 1.3 ports.
It's a little expensive, but worth every penny. I'm planning to get a 46 inch.
