Hello all, yes again same issue here. Just read all 13 pages of this which was fun!
Just bought a brand new 15" rMBP, 16Gb, 1Tb SSD and have reboots occur randomly overnight. In fact I left my laptop on to go to work today and tried to remotely connect through Teamviwer but could not connect. When I got home the timestamp on the Sleep Wake Failure report was indeed about the time I tried to connect.
I'm interested in the amount of people reporting that they happen to have WD Drives plugged in though USB 3.0, since I too often leave them connected overnight (and did so today) through a hub. 10.9.1 also for me clearly has not resolved the issue.
This new retina is replacing my non-retina 15" mid-2011 MBP which had no issues whatsoever with Mavericks and my WD hard drives connected (although that model doesnt have Power Nap) and that unit ran perfectly fine.
I'm going to leave my laptop on overnight with nothing connected and see if its still running in the morning and throughout the day. I've also disabled Power Nap so will report back tomorrow afternoon. (UK time).
