Damn, everyone is jumping on the Wii-train; If it's not Sony supposedly building a motion controller, it's Xbox Live reportedly rolling out Mii-like avatars.
That's right. Based on a cache of documents leaked over the weekend, it looks like Microsoft may be changing out gamer-pictures for fully customizable, animated caricatures just like Nintendo...and the PlayStation Home, for that matter. If the documents are to be trusted (they look pretty reliable, but this is the internet), it seems logical that Microsoft is going to roll out the avatars at E3. Supposedly, Xbox aims to combine the customizability of Home with the in-game play of the Wii's little fake guys.
We're going to reserve judgment-- although it's very very hard not shout "WTF?" at the top of our lungs---and leave it up to you, the readers.
