Yet more rushed Mario games that can't touch the quality of SMB3 and SMW, this will push 3DS hardware like crazy though, I predict even more so than SM3DL. I can see 3DS selling better in its 2nd year with this game. Add in a Smash Bros and they're set, the 3DS will practically just print money for the next 4 years.
I'd actually love to see DKCR 2 on the 3DS.
