Yes, part of this is us being super selfish and impatient. We want the new Zelda game, and we want it now, but there are several less selfish reasons to hope that Nintendo is going to release a Zelda game sooner than later.
Alright, one of the other reasons is pretty selfish, too: Unless there's a Zelda within the next two years, there's not much of a chance that there will be a second Zelda game on the console. Though Nintendo used to shoot out a new Zelda game every other year, it has been slowing down recently, with four years separating Wind Waker and Twilight Princess, and five between that and Skyward Sword--so the sooner this one comes out, the sooner the next one can come out. Besides that, though, we want one soon to help justify purchasing the Wii U. Nothing sells Nintendo consoles like Nintendo games, and besides Mario, Link is their biggest star.
