We all know Forum can't legally buy KVRR, because it and WDAY/WDAZ are both Top 4 stations. I bet FOX programming gets moved to a WDAY/WDAZ subchannel, most likely 6.3/8.3 which is in HD.
In the article it mentions KPTH in Sioux City IA - that's FOX; CBS is KMEG, owned by Waitt Broadcasting and run by Sinclair. You think Sinclair might move CBS to a KPTH subchannel like it's done in other markets?
