Well, one claim is that the iPhone 5 has already been jailbroken on iOS 6.0.2 (untethered), but they won't release it until iOS 6.1 is out.

The good news for Apple TV 2 owners at least is that even if you upgrade to iOS 6 (otherwise known as Apple TV software version 5.1.1), you can still downgrade to iOS 5 (software version 5.0.2) for the untethered jailbreak. Apple is still signing 5.0.2 for some reason, and I can confirm this because I was actually on iOS 6 (5.1.1) when I did my jailbreak.
ATV3 owners are still out in the cold though, regardless of what OS version they're on.
