I got my 15" MBP 2016 as one of the first as well. An important caveat when setting up your system is not to clone 10.12.1 from another system and expect no hiccups. I used an app called SuperDuper but this probably applies to CarbonCopyCloner as well. Essentially the image that is on the new Macs seems to have slightly custom drivers which did not make it into the 10.12.1 release.
Either use the official (and somewhat slow) Migration Assistant/Time Machine or after you clone your drive from the old machine, make sure to use Recovery Mode/Cmd-R and reinstall the operating system from the recovery partition. For me, though it took several hours to install, it quietly retained all my data and resolved all issues I had been seeing with stock macOS 10.12.1.
