Well, if you wouldn't play it now, I'd get it and play it on the Wii U if you get it. =P Plus, you could always wait a little bit, see the reviews, and then decide if you want it. As long as you don't care about the CD, of course.
Perfect for me, however, I only have one remote... Then I'd only need a Nunchuck, and I'd finally be able to do Multiplayer with remote-only games. =P If I can get it, however. =/
I definately won't be getting a Wii U... unless a massive pokemon game comes along and I inherit a great fortune. If I played Wii even weekly I might try to get one, but as it is I only play a bit in the summer and for about 2 weeks in the winter.
Yes, getting an extra remote and a game for $70 is a good price, so this is good for you. How many games need a nunchuck for multiplayer?
