"The following four programs have been encoded at 1920x1080 (1080i) and 1280x720 (720p) resolution for playback at 19.2mbps and 5mbps respectively. The 1080i examples may be viewed with the VideoLAN player (VLC) and the 720p examples with Microsoft?s Windows Media 9 player."
Assuming that they will have at least a 54Mbps wireless link on this thing, I'm sure that they can stream audio and video to the headset fine, especially considering you'll be in close proximity to the console probably anyway.
As I said in my other post, the implications and possibilities here are amazing. Add to that the possibility that this will allow someone to replay Metroid Prime in a VR environment and I can tell you right now that I will probably buy this.
I also suspect that Nintendo never really got over the failure of VirtualBoy, so what better way to prove to everyone that not only CAN they do it, they WILL do it again and this time they won't fail at it.
