Check the Wiki for all the info on it.
Fox only ordered 16 episodes this season, which is odd as every other season, and most other shows, do about 23-24 episodes. It's also going up against new CSI as well as Greys Anatomy. If it pulls in the viewers, they'll order more episodes. But give the dwendling fan response, the loss of viewers and the poor quality of the shows, season after season, I wouldn't bet on there being more episodes unless Season 4 is at least as good as Season 1.
