I would like to see JJ Abrams trek novels get released. I do not know why they have chosen not to release it. All it does is question the authenticity of the JJVERSE. Perhaps it is not really trek since they can not give it the same treatment as the TOS Universe.
It does nothing of the sort. The books are a tiny, tiny sidebar of the franchise. Authenticity in a franchise comes from the creators of the core canon, the ones responsible for defining and shaping the universe. Tie-in novels are just speculations building on what the core creators have established. Any legitimacy or authenticity our books have comes from their adherence the canonical source, not the other way around.
Besides, there are certainly other tie-ins to the Abramsverse. There is an ongoing monthly comic being written by an employee of the Kurtzman/Orci production company and vetted by Roberto Orci himself (at least nominally). There was the
Starfleet Academy series of young-adult tie-in novels, which ran for four installments, equal in number to the ones that were cancelled. There was a tie-in comic story published in
Wired magazine. There was a tie-in computer game, though it didn't do very well, I gather. And the first film had plenty of toy and merchandise tie-ins, more so than any Trek movie since ST:TMP in 1979.
So there's been no shortage of tie-in promotion for the Abramsverse, at least not for the first movie. It's just that the chosen emphasis for the tie-ins has gone in a different direction than we're used to, and the mass-market paperback novels that are such a longstanding part of the tie-ins for the original Trek universe ended up not being a part of the tie-in efforts for the Abrams universe. (Or maybe now we should call it the Abrams/Orci/Kurtzman universe -- the AOK Universe?)
