Actually Have they announced the capabilities of the Game DVR ?
I'm pretty sure all they've said so far is that it has a running archive of your most recent 15 minutes of gameplay (much like a Cable DVR continuously keeps a 15-30 minute running record). As far as pressing a record button to record an entire gaming session, that hasn't yet been announced, but I assume it will be there.
As for live streaming your gameplay... ustream and twitch are both on board as well as youtube (for those that have unlocked the ability for youtube live events).
is it 720p or 1080p ?
30 or 60 FPS ?
Also does twitch or Ustream allow for 60 FPS ?
I think these are all pretty moot questions, as even a couple of minutes at 1080/60p would produce files too large to manage.
Streaming depends on your upload speed. 1.5MBps (the average household upload speed) will only allow a low-to-mid quality 720p stream at 30fps. A full 1080/60p stream would require an upload speed of about 18-20MBps.
Here is something to tide you over, friend.
