One thing to watch is how Tribune Co. decides to position WGN America. If they keep the channel as-is, they desperately need the Cubs broadcasts. The Cubs -- and to a lesser extent the Sox and Bulls -- are among the few things that attract a national audience and keep the channel on cable systems outside of the Midwest.
On the other hand, there have been rumors that Tribune's new owners want to remake WGN America in the mold of TBS, with more original programming. In that case, they may want to shed the Chicago identity and drop the Cubs and Sox games, just as TBS dropped the Braves.
