A very worthwhile link. Thanks hupfinsgack.
Graphically, trying to read between the bad-compression lines, games look more advanced than just GC1.5. Elebits has quite a bit pf physics and showed the potential of combining physics with physical guestures. I'm not sure the game would be much fun, but for potential I think it bodes well for future games. Red Steel showed some nice effects graphically too.
I didn't understand the Warioware Smooth Moves. Was that a demo, or the actual game? As a game it'd give me a headache I think, with miniscule and inane activities - opening a lock with a virtual key is a game?! It did show different ways to use the Wiimote, and I hope that's what it was intended to show as a demo!
The plane game I couldn't figure out how it related to the Wiimote. On the occassions the Wiimote popped into view, it seemed to be being held cross the hand rather than along it, and controlled as though the wings of the plane. But the movements didn't seem to correlate.
This really runs into the key concern for the Wii - how does it control? Red Steel's camera movements seemed very rough and as an FPS it didn't seem to benefit from the Wiimote. The sword-fighting also looked rather stiff, but IIRC they've changed the sword-fighting since E3. Some of the Wario Ware moves looked a little rough too, and then some looked very smooth and well controlled.
I don't think there's any two ways about it. Wii is going to be something one has to try, and myself, I would want some long exposure before buying. I can imagine the controller feeling quite awkward on occassions along with the endurance concerns.
