News from the Quake Live front being hard to come by for some reason, here's a brief mention of it from an interview over at 1up.com....
Yes. Well, the current Quake project is Quake Live, and we're actually doing that internally as well. But that's multiplayer-focused, obviously. In terms of what happens next with Quake, a lot of that will depend on how the reception for Quake Live goes and whether that team continues to invest in building that out. That would be what we're hoping for, and then [we'll] figure out where we go down the road with that.
The Quake Live team is smaller. We're still not fully fleshed out [with] three teams that can work on three projects simultaneously. Even then, then you've got Doom, Quake, Wolf, Rage -- it's like there's still an odd franchise out. Plus Enemy Territory, which would lend itself with working with an external party.
