I think this game's kinda straying from the classic "Zelda" theme with the whole aliens from the digital realm thing. I mean, Zelda has always been about fantasy, as opposed to sci-fi.
I dunno, though. I'm sure Nintendo will pull off something great. I mean, they managed to move away from the classic graphic styles for Wind Waker and still make it a great game, so maybe moving away from the classic environment scheme for one game might be interesting, as well. Either way, I can't wait to get this game.
Also, there's rumors floating around that when you pre-order the game, you'll get a special bonus disc, (like when you pre-ordered Wind Waker, you got OoT and Master Quest) and it will have the Wind Waker game done in the new graphic style, as opposed to the cel shading. Has anybody else heard these rumors, or is able to confirm/deny this? If this is true, then buying the new game would be worth the new Wind Waker, alone. =P
