There's a big Quake III Arena feature on PC Zone offering a look at id's upcoming shooter (note: since this story was posted, they've added a registration form, so you have to submit info enter the site now). The piece has a Q&A sidebar with John Carmack that includes some subjects like John's favorite games, and his one fight in high-school (a victory no less), as well as a load of answers from members of the id crew to various questions about the game. Also included are several screenshots of action from Q3A. Here is a quote from John Carmack about the state of progress in Quake III Arena in the war against 'net lag:

Carmack: "Jerkiness is the characteristic of Net play that has been most improved. Almost all visual effects are either cued for local running, or presented in a parametric or other extrapolatable form, so that when packets fail to arrive on time, most of the world continues as expected without a visible hitch. Of course, if your Net connection really craps out and you don't receive any new packets for several hundred milliseconds, the action will reach the reasonable limits of its predictability. Perceived lag has been decreased by allowing more actions to be handled completely on the client side, without having to make a round trip to the server. Weapon cycling, falling/stepping/ walking view feedback, and weapon muzzle flash/sound feedback are all done locally now. The actual effects of your actions on the world and other players still requires a round trip to the server, so lag isn't gone, but it is improved over all previous efforts
