Don't think this was posted. Gamesradar round-table, they basically try to review it in general without reviewing it, if you get my drift.

They gravitate toward Fighters Uncaged and Joyride as the better games (they don't appear to have had Dance Central). But overall it doesn't sound very encouraging at all.
edit - don't know why MS didn't go with the same 'mirror of you' concept for interface stuff as eyetoy. Sounds like they're trying to be fancier and it just doesn't work.
