Add to this with your speculation on which wireless regions will end up combining.
I'll start by saying that I speculate that New England, NY Metro and UPNY will combine. I also think Philly and DC/Baltimore will combine. Down south, I expect Tennessee/Carolinas to stay on its own, but for Alabama/Georgia and Florida to combine. I saw in another thread that there's speculation that Houston Gulf Coast and Central Texas will combine, and that's rational to speculate.
Midwest will likely see Michigan/Indiana/Kentucky be split between Ohio/WV/PA, Chicago/Wisconsin, and KS/MO. Not sure what'll happen to Great Plains.
Out west, I think Southwest will go to Mountain region, California/Nevada and Southern California will combine, and PacNW will be left alone.
What's your speculation?
