I just spoke with my anonymous source who for reasons of protecting my relationship with them & vice-versa, I can say no more. The bottom line is no confirmatory information regarding the timing of release, the version number, etc. is going to be released to users at this point for a variety of reasons. Thus, I'm going to sit back & cool my jets & just wait as any specific answers being provided to us, or anyone else, are simply not sanctioned. I can assure that I'm not 'blowing smoke' as I have the utmost respect for this person & will leave it at that.
Without being too specific, is it worth rooting and ROMing at this point, or is it still worth waiting?
"no confirmatory information regarding the timing of release, the version number, etc. is going to be released to users at this point for a variety of reasons"
This hints at the possibility that the update is not yet ready for prime time.
