If I were to guess a while if not never seeing as he is working on a source built ROM currently. Which mind you IMO is a better deal then dealing with the leaked Moto/VZW Official build which is what frf84b is
From what I'm told from where the leaked file came from the proprietary files in frf84b are the same as the last leaked file tho as nothing has changed there recently.
I compiled from source last night with FRF84B proprietary files and FRF84B gapps. Yes, source builds IMO are always better and it is running hacka nice right now. I have really all the features I want and am ready to start applying themes.. should be out hopefully by Saturday if not sooner.
