Good to have more confirmation of the wireless nunchuck then! Well, now this went from "sort of want" to a solid setup and seemingly an improvement even over the Wii. I just hope they will have some worthwhile games, not mini-ventures, on show to push it.
It would make sense to have Triangle and Circle on the Wand and Square and X on the nunchuck I think.
There was a questionmark after my sentence, so it was just wishfull thinking, but since R3 and Killzone is Sonys only first/second party FPS, I recon there is a strong will inside SCE that they should have a controlloption for the Arc. And I thought R3 was a sure fall 2010 release , looking at Insomniacs releaseschedule, but as some of you said, there hasn't been any confirmation about that.
I think we'll see Sony really playing up the Camera and Augmented Reality aspects of Arc to try and set them selves apart and or ahead of the Wii'mote. But as with everything else it'll come to down to the software.
Also I wonder if Killzone2 could even be patched to use Arc. I can imagine the PSeye and Arc occupying a SPU and some system ram. Could you get something as good looking as KZ2 or Uncharted running while the Pseye and Arc are being used?
