Very neat concept.
Here's an idea, instead of taking votes from just your emails, you should tally up votes from the reviews here. If you do decide to take my advice, then I vote for the Wii.
So as for reviewing, it's very cool. Great graphics, not much on sound since its just music at the moment, but good style and animation, very shiny. I like shiny.
Looking at the contestants, since the 360 looks like a white w/green Master Chief/SPARTAN, then shouldn't the Wii look like a white-clad Samus? Dunno what the PS3 would look like, but the Wii-bot could look more like Samus. the remote's buttons could be on the arm cannon, and the Nunchuk could be like the grapple beam, but still usable like, well, a nunchuk.
Y'know... a Wii remote would make for a great laser sword, too.
But all that's just some ranom babblings from a reviewer. Great animation, can't wait to see the final battle, and I hope PS3 doesn't come out on top (seriously, it isn't nearly as impressive as Sony is trying to tell us it is).
