If I had to base my opinions on what I've seen thus far, I'd be on the fence for scrapping the project in terms of Zelda. It was going a good road, but it seemed to have lost some steam. I was extremely happy with how TP's motion controls panned out. The only complaint was the accidental spin attacks when trying to shield bash. Other than that, the controls met and exceeded my expectations, making it simple enough to learn the WM mechanics and still incorporating old button pushing mechanics. But SS came out, and while they were done really well, their controls didn't feel like they had anything too revolutionary about them. Don't get me wrong, I can clearly see the advancement between SS and TP, but the step SS took with motion controls didn't seem big enough. The biggest problem is probably variety. I can only swing the Wii-Mote and time the nunchuk so many times before I start feeling tedious. Motion controls require a bit more work than button pushing for the player, so if there isn't an atmosphere that makes performing the motions naturally, it can get tiresome. Give me something more than just the finishing blow and the spin attack to make me feel like I'm being creative/instinctive with my thought process. Of course, I'm smarter than the average Random Person (or atleast have a different opinion from him) so I know that there is huge potential for motion controls and thus don't just base my opinion solely on whether or not it's Tuesday. While SS didn't take a huge leap, it still made progress forward. I'm constantly waiting for the day when virtual reality is real for games. Not to mention, games like Wii-Sports and others are proof that sophisticated motion controls can really enhance gameplay.
So I don't particularly need motion controls, especially in my Zelda game, but I see the huge potential that they have. The key to them is to not make them feel gimmicky, but that the controls are a natural part of moving forward in gaming. If Nintendo brings back SS's motion controls, but focus on more ways to apply them to gameplay instead of just more ways to apply them to the game, then I'd probably be crying over the beauty the game would produce. Can you imagine TP's sword moves with SS's motion controls? Epic.
