Probably for WoW-type games where most of the content is stored locally 
this is true. For Second Life type environments, where geometry and 
textures get streamed, bandwidth is going to still be an issue for a 
while.

Are there headsets for consoles?

I'm really not seeing anything particularly compelling there. Maybe 
MPEG-4 might gain some traction for the sort of simple little games 
people presently implement in Flash. This isn't exactly going to be a 
major shakeup.

Sure. Just don't expect people to use this kind of thing as a substitute 
for web browsing.

Because, you know, when a technology stagnates for a decade, coming up 
with a buzzword-compliant replacement with a new name always turns 
things around.
