If there's no cel-shading, how is it the same engine?
And Tosoto, graphics may not "make" the game, but they can definately break it, and IMO, cel-shading was a bad idea on Nintendo's part. I think they thought so as well, which is why the new Zelda will not be cel-shaded. Just because graphics don't make the game doesn't mean it's ok to have crap graphics. New game consoles don't increase the story of a game any. nor do they increase the available features in a game much, that's why the main reason to buy new consoles is to get games with better graphics. You could put Windwaker on the N64 and have the exact same story and features...and pretty close to the same graphics, if not exactly the same, without much problem.
