Upon checking the nextgentv website, it's "coming soon", but I couldn't find anything on either rabbitears or Wikipedia. A pattern I'm noticing is that low-power stations tend to flash-cut over to ATSC 3.0, (in my case KBRO-LD, an infomercials channel) and full-power stations will combine in another channel (In my case, KWGN (CW 2) {RF 34} became a next-gen host for itself, as well as KMGH (ABC 7), KUSA (NBC 9) and KDVR (FOX 31), and in return, those station's ATSC 1.0 signals now host KWGN's subchannels). So the way I see it, WATN could possibly become an ATSC3 host for WMC, WREG, and WHBQ's main 1.0 signals, while these stations in return could hold WATN's 1.0 subchannels.
