Most shows are on temporary hiatus until the strike is resolved. Shows with lots of fixed sets are at biggest risk of being cancelled due to rental costs of those sets. At this point, most shows will not complete their full 20-something episode seasons. Those that will are the ones that have been delayed, ones that were done ahead of time, or ones that aren't part of the WGA strike. At this moment, many shows may lose their original timeslots because of reality TV shows.
