I agree with all those that say they should market the "free-style" controller as hard as possible.
If anything, they can just show the "wand" sliding into the controller shell at the end of the commercial, but only as it mentions that it can play games from past generations.
"With the shell attachment, the Revolution controller transforms into a suitable controller ready to play all past generation games, including the NES, SNES, N64, and Gamecube." -- During that you could show exactly how the controller fits into its shell, then people playing Super Mario, Super Punch Out! , Goldeneye, and finally Zelda: Twilight Princess, of course all wirelessly. This could all be showed in 10 secs or less.
Detailing the possibilites of the REV controller and showing examples is first priority. Once that's done, run something like I mentioned above.
If a commercial (or better yet, a before-movie trailer) like that ever saw the light of day, it would have people drooling.
