While I actually like the idea of non-glasses 3D, gonna say that pumping the technological aspect is a major problem, like the issue with Hollywood. Instead of investing time into engaging gameplay, Nintendo is taking the easier route of gimmicking the technology to create the illusion it's progressive. Granted, it's a tougher route than hiring some unemployed FF fanfictionist to write a sap story for a movie-game, but more challenging gameplay for new games would be better welcomed than the visual makeover.
I mean, OoT is still OoT, 3D or not. Until gamers are actually riding Epona or simulating intercourse with Ruto, I'm not going to be moved by Nintendo's efforts to bring its games into the third dimension.
