Obviously this was bound to happen eventually but...
The CW **might** be on the move in San Diego as soon as next Monday. Spectrum and Zap2It (Gracenote) listings show CW programming airing on KUSI, with KFMB-DT2 moving MNTV programming to 7-9pm, moving their 10pm news an hour earlier.
However, TitanTV listings don't seem to agree, there hasn't been an official announcement yet, and it's also only March (Nexstar usually does the switches in September, which is also when KFMB's CW contract officially expires). It would be weird for multiple schedule providers to make a mistake like this though, so I doubt they're incorrect
