Hey Brent - thanks for the insider info... Something to remember though is that it usually takes 4-6 weeks for TA of a software package, so if the "November or December" release on the Microsoft site for TP2 updates is correct, we should see something in the system soon.
I can tell you one major sticking point right now is that the builds for 6.5 are not working correctly with Rhapsody/VZW music service (the software doesn't recognize the device as something that can carry the Rhapsody to Go licenses) so even though VZW isn't saying it's a "RTG" capable phone, users that are already on the service will blow up if they can't get it working with the "update"...
Keep us posted if you see anything cool though!
