Okay here's what I will do.
Metacritic
Zelda U>Uncharted>Halo
Sales
Halo>Uncharted>Zelda
Now here's the logos here. First off, for those of you predicting 2-3 million for zelda because it isn't "dark and gritty" just remember that that has no effect anymore. I'll bring my points.
The original Wind Waker sold >4M for the gamecube. It sold 1.22 million on the Wii U as of May 7. That isn't considering all that came after Mario Kart, and the digital promotion. The difference between then and now is that now people love the "cartoony" art style, as long as it brings a good game.(Phantom Hourglass sold well because it was literally targeted at kids) Another thing is that Zelda is entering the "big world" competition this time that people seem to be going crazy about these days. I think it can at least sell 4-5 Million lifetime. But it is still last in this comparison, simply because Halo is known for selling well, and Uncharted is a good game with a high install base.(It will sell even more if they do a collection of the first three Uncharted games for the PS4 *wink wink*)
As for Metacritic...is there any doubt? Naughty Dog is an excellent studio, so of course they will deliver a good game with a high score placing them in second. Zelda is 100% KNOWN for having high metascores. I'll list a few here.
OoT 99
TP 96
WW 96
LttP(GBA (Lesser port) 95
MM 95
I do, however, think it will be a close match with Uncharted if they can pull another Uncharted 2(96) But that is on and off because Uncharted 3 is 93-92(can't remember) and Uncharted was <90
