I'm seeing the same issue, this morning it happend to me where ater 70 minutes asleep in my bag it woke up with:
11/15/12 5:59:33.000 AM kernel: AirPort_Brcm43xx::powerChange: System Sleep

It then spun in my bag, heating up, and was completely unresponsive when I went to use it until I did a hard boot. Has anyone else found what is going on here?
In the end I just format->reinstall which solved the problem.
I had applications such as a graphics card switcher and some other notification apps (growel for example) which I haven't installed this time round.
Reinstalled DropBox which hasn't effected it.
I saw exactly that same problem this week. Put MacBook Pro 15" SSD to sleep, got on an airplane. A couple hours later took it out to do some work, and it was hot and unresponsive. Power button would not revive it. On the ground, I plugged it in to power and the power button woke it up. Battery was down to 54%.
Today I experienced the 70-minute unattended wakeup problem. I had put it to sleep and in my bag. A couple hours later tried to wake it up and it would not. It was NOT hot. Holding down the power button caused it to boot (not wake up). Console showed it had woken up 70 minutes after I slept it, with nearly the exact same messages as above.
Preferences > Energy Saver showed no wakeup schedule. It did have Wake on Wi-Fi, but that's under Power Adapter, and it was not plugged in.
This is a new machine which I have had for about 4 weeks.
I'm getting something similar. Around 3 hours after I manually put my MBP Retina 15" to sleep it wakes itself up with:
13/02/13 2:37:28.000 AM kernel: Wake reason: EC.SleepTimer (SleepTimer)
13/02/13 2:37:28.000 AM kernel: AirPort_Brcm43xx::powerChange: System Wake - Full Wake/ Dark Wake / Maintenance wake

13/02/13 2:37:28.000 AM kernel: en0: 802.11d country code set to 'X3'.
I have wake from sleep for network activity disabled. But I also have in "Energy Saver" to never go to sleep when plugged in (since I often run software tests over night and don't want them interrupted). I have now reenabled sleep so hopefully it will go back to sleep at least. But I'd really like to know why it is waking up!
I have DropBox, RescueTIme, Everynote, Growl 2.0, Messages running normally but I don't see how any of them could be related to SleepTimer... Anyone else made any progress?

I was just reading more on this and saw that BlueTooth devices may be a problem. I have an Apple Mighty Mouse so I thought it probably is not that, but I just found that I have "Allow Bluetooth devices to wake this computer". I'm turning that off now and will report back if that fixes the problem.
In my case, the problem was traced to the Casper administration agent from JAMF Software, loaded by my company on all Macs. It was a known problem, and applying an update solved the problem. If your Mac is centrally administered, check with your IT support team to see if this or any other remote administration agent is installed.
