As for the games above, I love each and every Zelda shot that comes out, but I think Nintendo needs to start showing something different. I can't help but look at those images and think of the game as Ocarina of Time with a face lift. It was fantastic to see these sorts of images last E3, tying the game to arguably either the best or the second best of the series, but now's the time to show how this game's unique. God, Nintendo, get the hype machine pumping! You make good games, so talk them up!
I think the new gameplay will come at E3 when they will likely have a playable Zelda on the show floor. I think they initially said no more Zelda stuff until E3 anyway so I look at these shots as a bonus. The early announcement effectively said "yes, we're working on a new Zelda, and it will be closer to OoT than WW, now let us get back to work."
