I think it is a pretty innovative concept.
We don't play our Wii nearly as much as we used to, but we like it. We also understand what it is, and isn't. We got it pretty much for extra family time stuff that we and the kids could play. Wii Fit is pretty cool, and we have the kids version of the Fit as well. I have Madden 2011. I haven't really had the urge to break out the old PS2 or anything since we've had the Wii, so it's not all that bad. The new one looks pretty cool.
