LG G2 Update to Android L 4.5/5.0 "Lollipop" Confirmed

Any news on Lollipop from AT&T for the LG G2?

If I have an unlocked AT&T phone, can I install Lollipop from LG or from Google? Would either LG or Google offer a version for installation to end users? I would not expect LG to offer anything except for model-specific updates. But Google? Probably not, also.
