It would certainly help sales. And the game could be bigger/better. I understand their logic, 3DS is the hot selling handheld, where the series has made it's bread and butter. MH3 did really well on Wii, but I'm sure they want to continue their portable success.
It wouldn't kill them to make a Wii U port of 4 though.
