Don't think it's officially out until tomorrow. The dates have been back and forth from the 16th-18th. However, it's on my radar. I don't expect anything revolutionary. However as long as the motion controls are acceptable it looks like some unique mini-games to play around with for less than $40.
I plan on getting it tomorrow. Perhaps I'll write an impressions. (Unless reviews come out and say it's terrible and broken) - which I am 1/2 expecting seeing "Game Partys" track record.
