Nothing from Scripps, other than a rename of Doozy to TrueReal in late March.
Defy TV and TrueReal will likely launch on Ion stations, replacing the QVC and HSN subchannels, per RabbitEars, but there are uncertainties for the Ion stations that were spun off to Inyo Broadcasting, and for those stations that don't run the standard 6 subchannels. I'm guessing that where Scripps had to spin off the Ion stations to Inyo, they will still allow Inyo to have the two new subchannels instead of putting them on the Scripps stations, but that's not guaranteed. For the Ion stations not running the standard lineup of 6 subchannels, they may add a new subchannel. It's all conjecture at this point, as Scripps hasn't published a word about their plans.
My home market of Phoenix has a unique situation in which Scripps owns KNXV-TV and recently acquired KASW from NexStar just before the Ion deal went down. The Ion station had to be spun off to Inyo, but doesn't run the HSN feed on the .6 subchannel. Meanwhile, KASW was made into a NextGen lighthouse, so its ATSC 1.0 feeds are dispersed among the other stations in the market, so that's not a good option for Defy or TrueReal. The subs that KASW and KPPX run are duplicated on other stations, so who knows where Defy and TrueReal will end up.
