For my part, I don't want motion controls for simulation, at all! I want motion controls for immersion, not for replicating motions I can make on my own. There are people out there who do want to feel like they're swinging a sword, or shooting an arrow, or punching a guy in the face (boxer, I should say) - I am not one of those people.
I'd like motion controls that offer a different take on gameplay settings, ones that at least come close to having buttons for instantaneous input. But, buttons remain important for certain things - if I'm waving my arm to jump in a platformer, or shoot in a gun game, it had better work flawlessly, or it will ruin the entire experience. This has been shown to work, in the past - just look at the Metroid Prime Collection; changing the camera angle or where your crosshairs lay on the screen is intuitive. What few motion controls there are in Mario Galaxy or NSMBW work well, too (although Lost Winds is a better example, or And Yet it Moves - both are platformers with unique motion controls that work and are a blast to play with).
What I'm looking for in Playstation Move is not simulation, but a different gameplay experience. If Move combines the advancements in motion technology from Wii and 360 (motion control and camera sensitivity...to try and sum it up in two words, anyways - Move has the motion controls and a camera to interpret depth), then we should be seeing games that are far different than what those two systems can offer. That's how I see it, at any rate - I'm not investing until I see a game that offers something truly different, not another simulation...something like 'Sorcery' (I think it's called).
Looking forward to it, but not excited, just yet!
