Nintendo should change Zelda to keep it fresh, not to appeal to non-gamers. In their attempt to widen the audience of their existing franchises, Nintendo has made series like Zelda, for example, way too easy. I guess I just want Nintendo to create new franchises whether they be for gamers, non-gamers, or both. I know I'll probably get slack for this, but I don't think Nintendo should "compromise" (for lack of a better term) their old franchises by trying to attract non-gamers. Series like Zelda appeal to a certain audience and they should be made specifically with that audience in mind.
Anyway, as for E3, Super Mario Galaxy really wowed me. I'm looking forward to it much more after E3. So, no, I wasn't disappointed at all. In fact, I just reserved both Mario Kart Wii and Wii Fit yesterday. I'm happy with what was shown. Nintendo can't blow people away every year, but they can still have a very good showing.
