I'd rather have OTH in hiatus for a bit than have it have to compete with holiday programming or sports. That's one of the reasons for a hiatus. The other is for production to get a chance to catch up. Though it would be nice to have a clear run of episodes, I think it would be nearly impossible unless a season was completed a year in advance.
For OTH, I think filming wise, they're up to episode 713 or maybe 714, and then take a break for Thanksgiving for a couple weeks. Then back for a couple and off for Christmas. Gives our guy, and the cast and crew time to celebrate the holidays too.
Doesn't 24 return in January? Didn't that conflict with OTH for you? It shouldn't now with OTH on an hour earlier right?
