If you could somehow get your hands on a Wii, I would say buy a Wii and give it a test spin. If you didn't like it, you could sell it on ebay for more than you bought it for. Right now, the Wii and the PS3 are still in their infancy. If you want good gaming right now, this instant, 360 is the best option. If you can wait, keep your eyes on all 3. They will be getting some great games come this fall.
