The controller seems to sport not only what looks like a Move sensor on top, but a small touchscreen right in the middle of it. Potential functionality aside, it certainly doesn’t look appealing. Then again, it is a prototype, and there are always ugly prototypes.
If that is a Move sensor, I can only imagine how awkward wielding that thing is going to be. I’ve never been super comfortable with the Sixaxis controls. And a touchscreen? If it works, it works, but I hope they’re not just jumping on a bandwagon. Bandwagons rarely go anywhere good.
