According to
these articles, Fox plans to pre-empt Futurama during the April-May sweeps period (replacing it, of course, with reruns of The Simpsons) and then run the remaining episodes over the summer. I mentioned before that ABC did something similar with The Critic: they showed it in the early spring, cancelled it, and ran out their remaining episodes that summer.
Apparently Fox will run lots of other new stuff over the summer, including the new series Keen Eddie, more Temptation Island, and several new reality shows, including Junior American Idol (no, I didn't make that up).
If the stories are accurate, it seems that Futurama will finally be on a regular schedule, even though it's only for the show's last six or so episodes. The scheduling problems would reach a new level of silliness if the show still gets pre-empted over the summer, but I wouldn't be surprised.
