So... ID thinks re-releasing a 10 year old game with no mods or custom maps will draw a ton of people and somehow be a commercial success?

They want a game that is played by A LOT of people, so they will have revenue coming from from the ads in the game. And for that to be successful, you need a lot of people playing the game other than the 1500 hardcore quake 3 players that played the game for 10 years. Throw in some complete noobs who, by quake standards, have no reflexes, movement skill or aim, and you'll see them flee away after getting slaughtered in the game over and over.

Oddly enough, Carmack actually had the nerve to say, "I'd say probably the success of Quake Live is going to determine whether or not we do another Quake Arena project."

It's a big fuck you to all the fans of the quake franchise. There is no reason why the next "decent" quake game shouldn't already be in development. The longer they re-hash an old game, the more fans they will lose out to other games, and the seemingly less likelihood that we will ever see another quake game.
