I don't see why they should have to when the other companies do not have to pay for ports, that's a bit absurd.
If Nintendo is going to shell out cash for games to be made for Wii U, they should be (GOOD) exclusives. That brings more value anyway. They've already done a bit of that (Lego City, the NGIII "improved" version, Bayonetta 2, Devil's Third).
Wii U needs more ports, yes. But there is no way Nintendo should have to pay off anyone to get something other systems are getting "for free".
