For myself in Phoenix AZ, I still have most of my channels working but 2 of them are not, Fox 10 and NBC 12. I did not recieve any Beyond TV notice that my lineup had changed so I assumed it has not yet changed. After a manual scan for guide updates there were still no changes.
So I guess we wait and see when Zap2it will send an update? Or if they did I would assume the 2 channels did not make the switch?
Just my 2 cents.
Update:

Some channels are not switching until a few months later.
