Same here in Los Angeles...I was channel-surfing the other day, and Laff was already on KPXN 30.5 (and still carried on KABC 7.3)
I think Univision may be the big loser in this scenario, as Bounce, Court TV Mystery, and Grit are carried on Univision/UniMas O&Os in many major markets including both in Houston and Los Angeles. However, Univision/UniMas O&Os still have GetTV, True Crime Network, and Quest on a lot of their stations for the time being.
Nonetheless...ABC, Nexstar, and Univision probably should start getting more creative for programming options (either by creating a new diginet, or even in Disney's case, maybe re-introduce ABC News Live as a subchannel in Laff's place), particularly if they want keep their retransmission revenue for these extra channels.
