Heh, I don't think we europeans have any more info about the game itself but atleast I was able to preorder it.
Comes bundled with the wiimote and costs 56.90 €
I don't know if the game is any good but buying this pack along with a Nunchuk is only 3€ more than the Wiimote+Nunchuk.
There is some info on Wikipedia: http://en.wikipedia.org/wiki/Wii_Play
I think this pack sounds cool
