I really want Super Mario Galaxy 2 in HD, retail.
The game seems to be the magnum opus of the Wii and 3D platformers in general, I'm finally getting back to the original after ages, I wasn't hooked like I was with Sunshine and 3D Land, but it's finally growing on me.
SMG2 looks much better, and has Yoshi to boot.
This game could truly shine on Wii U in 720p/1080p with AA. They should release it alongside NSMBU, and for really cheap (like $30-$40, depending on the price of the games if they go HD tax on us).
Should take EAD Tokyo no time flat. The game should work on the pad, does Yoshi's tongue require the pointer? They can work it like Sunshine and just home-in on the nearest target.
