Like _D4V1D_ said nothing official however IMM26 that has been leaked appears to be signed with production keys and not test keys. I can't find the exact thread now back over at xda-developers but they are sayings its probably as close to perfect as you can get and appears to be the best canidate for the OTA if you haven't already oem unlocked your phone.
I do appreciate the info thank you. Am just so tired of all the rhetoric bull we are constantly fed about being the first in line for all updates and all that honestly I dont think we will see it. The way I understand if we use the release thats out it will void our warranty so whats the use, not gonna buy a galaxy nexus if this keeps up they did the same thing with every phone I have had. To poi.t of being absurd.
