on my 2013-02-26 bill for service in Chicago Area 2:
Recently WOCK-TV made programming changes to several of its channels. WeatherNation TV is now available on Limited Basic channels 392/690 (replacing AAN) and Veria Living is now available on Limited Basic channels 389/596 (replacing LATV). WeatherNation TV provides local, regional and national weather and Veria Living is a health and wellness channel which offers programming for a healthy lifestyle.
NOTE: beginning 4/16/2013, WeatherNation TV will only be available on channel 392 and Veria Living will only be available on channel 389.
No mention was made of carrying LATV from W25DW. Since AFAIK there are no W25DW channels carried on Comcast, I guess they're dropping LATV. Nor were there any specifics about ending any other duplicate channels in the current lineup.
