I'm still surprized they havn't made a head tracking unit. The Wii is already set up for it and it wouldn't be expensive to make at all(except for requiring an extra Wii remote) It's not even computationally expensive as the Wii remote itself is fully capable of tracking the LED's with little help from the console. It just seems like it would be only of those "blow everyone away" things. Whether games could make good use out of it or not would be another story.

So much good stuff here. Zelda and DKC Returns are the titles I'm looking forward to the most, and it's great to finally see a new Kid Icarus.
