About $80.
1$
A Wii 2 has not been announced yet, so getting a pricetag would be impossible.

If your looking for the difference if you trade in your wii it would be about a 100$ to 300$ depending on ps3 model or bundle. I hope I helped.
70 dollars
The fifa 11 on wii would probably have OK graphics, but xbox and especially ps3 would have much better graphics.
If you have driven before in real life you would probably prefer the Wii wheel however since its motion sensitve like the wii remote it can be faulty at times the classic controller would be better off.
