Best technology at E3 this year?

"Wii fit heart attack indicator." <-- That was hilarious.

Right now Natal looks like the best technology, probably because it is so different than what has come before and was sold fairly well during the conference. But, of course, we'll have to see how these technologies eventually pan out, which will likely be quite different than how they were presented a few days ago.

After getting a degree in Interactive Arts, nothing has that magic anymore. The brawn behind Natal just lies in algorithms and not technology. I'd be willing to bet you could put your own Natal together for very cheap, minus all the cool recognition, but with the exact same cameras.

Wii was magical when we first saw it. The indicator doesn't really do anything special - neither does the balance board. Sony's technology was just an afterthought to the Wii.

None of it matters unless somebody launches a console with it like they did with Wii. Wii sacrificed a lot to get where it is.

So, my answer is none.
