I'm still curious whether or not it'll be using the top screen's 3D effects-- if so, it'll have at least one edge over the Wii U release. Plus, it'll finally fill the void of not having 3D Classics releases of any of the NES SMB games. Sadly, the lack of any newly added background graphics for the NES skins (which would help prevent "ghosting") seems to suggest it that it won't.
