I don't think the graphical change is a big deal, the only thing that could possibly ruin any part of the game would be if they had a ton of stupid cartoony cliche things (I dunno how to do the little mark above the letter)...
But right now, I think this could be like the best zelda game...
take kind of a Link to the past enviornment and style, add in OoT kinda 3D gameplay... y'know... goody goody...
I just hope they change Link's appearance a bit...
