Dish is still "perfecting" the algorithyms for encoding HD locals into MPEG4 using ABC, CBS, NBC and FOX. They appear to have left two slots open in each range to add two more HD LiL's for each city. Perhaps CW and PBS will fill these slots. HD LiL's are reported to have many problems at this time.
WB is going away in September and CW will replace it, but stations will be shuffleing all over the place. Don't look for anything until after then.
