Also looking pretty sweet is the new Metroid Prime game, Metroid Prime 3: Corruption. This, of course, is only on the Wii and looks like it will give the Master Chief a run for his money. This one debuts in August (whereas Halo is in September). Playstation3 doesn't exactly have a franchise game to compete with these two. There's Grand Theft Auto IV, but that will also be available on the Xbox. Sony probably would've been wise to fork over the extra dough to Rockstar Games to get the exclusive rights, but their loss is my gain.

The premium on getting a Wii is pretty much nothing at this point (they were going for $500 on eBay a few months ago, now you can snag them for only slightly more than their $250 retail). So get out and game; but don't sit too close to the TV playing on your new system. Otherwise, you end up looking like this:
