Yes, I was purely being facetious. It will air. The network has already paid for all the flights, all the crew, all the permits, salaries, etc. They wouldn't do that just to shelve the season. Sure some shows are yanked prematurely for lousy ratings, but this show has been on for 15 years: CBS knows what to expect.
If it were pushed to summer, it could literally air any night of the week. Yes Big Brother airs 3 nights a week, but not for the entire night, and TAR has been paired with BB in the past. I think its very possible that season 30 could air in the summer if 29 airs in Jan/Feb.
