I don't recall Monster Hunter 3 moving that many Wii sales in North America. And I doubt it made enough long-term fans that they'd be willing to buy a new console just for an updated version of the game they already have.

Bit optimistic, no? But it is a change from all the guys proclaiming its doom, so I thank you for the breathe of fresh air. Monster hunter sadly, has never been that popular here, but it and Lego city should move some units, just not the numbers you predict. It'll likely be, say, around 500k total?
