Super Mario Galaxy rocks (so much for modern mario games stink).
However, I would love to see a new storyline besides Bowser and many of the SMB2 characters deserve a return.
And PLEASE for the love of God put the koopalings back in the next major Mario Game. I don't care if Bower Jr. is with them or not but they deserve a return and it doesn't make much sense in the storyline unless Mario killed them all in SMW.
