On my radio, things are different. For a day or so, Area 1 - Central went back to the conventional channel / talk group (00080), but today, it is back to the secondary channel (14736). Area 2 - East is still using the secondary channel (14768), instead of 00048. Area 3 - Mountain is continuing on 00112.
Good call I didn't notice this as I normally ignore those talk groups (esm) and they are patched so I can still hear them.
Looks like they have 2 patches active
Patch 1399 with groups 14736 and 80
Patch 139B with groups 14768 and 48
This along with radio testing they may be preparing to move some users over in the near future.
