I don't know if there is a date, but I imagine you could just call it the "Scouts BSA Handbook" and I think most folks will know which book you're talking about.
Making an assumption based on the release of the Cub books less than a month from the official start date, I wouldn't be surprised to see the Scouts BSA books show up in January.
related/unrelated question. Is there a date for a new handbook for 11-18 scouts to arrive? (not sure how to state that without saying boy scouts and being clear enough that I"m not talking about the various cub scout programs, LOL)
