A lot of shows are doing that now. There must be a reason for it. I guess since they don't do 23-25 episodes seasons, they stretch it out so it doesn't seem that long before the new season starts. May have something to do with ratings and sweeps.
They do that to stretch out the season for the entire year and for sweep weeks which occur in February, May, July, and November to maximize their advertising revenue. Feb. May, and Nov. are thought to be the most important. The first half of the WD seasons air in February, and the second half airs in November, both during sweeps time periods.
