What does NSMB for Wii U need?

NSMB on the whole has been a disappointment for me, because instead of being a true successor to the originals, it's just a lazy mishmash of elements from Mario 1-World and relies mainly on nostalgia to keep gamers interested.

How about introducing some completely new gameplay elements, and not just a couple of new suits that suck hard (penguin especially).

How can it be relying mainly on nostalgia to keep people interested, when somewhere around half the players are unlikely to have played 2D Mario games back in the day? There are 16 freaking years between Super Mario World and New Super Mario Land, they're not all the same buyers. Add to that the fact that NSMB is looking to sell around 50% more than SMW did, which is the best selling of the old Marios, and it gets even odder. (I'm excluding the original SMB here, for obvious reasons)

If it attempted to just rely on nostalgia, I don't see how it could avoid being a huge miss sales-wise.
