Speaking of Metroid: http://wii.ign.com/articles/815/815424p1.html
As said many many times, give developers time.
This is probably the first review of any Wii game I've read where the reviewers didn't have gripes about the control scheme in some way shape or form.
If you're looking for that kind of super precise controls, go out and buy Metroid Prime 3. Apparently this is just the start, given the other games up for release with the same super tight controls.
This will be very interesting if this is true. As a side note, I've learned a long time ago to stop trusting IGN when it comes to Nintendo reviews/previews after the Gamecube and lots of wasted money on titles they strongly enjoyed.
I watched the trailer for MP3 on my Wii, and I'm not sure why it didn't grab me. Perhaps it was the duality of the exciting music and the mostly meandering gameplay clips that didn't mesh right, or perhaps I'm spoiled by the brilliant trailers for Bioshock and Gears of War. But my excitement for MP3 is below what it was for MP2 which was below what it was for MP(1)...and I'm not sure that's far from most people.
I think MP3 will sell pretty poorly on the Wii, compared to other "top tier" games for other systems. Too many people are buying the Wii to play bowling vs playing an oldschool-revisited game like MP3.
