The real answer to your question, though, is that at the end of 2008, editor Marco Palmieri was laid off, meaning where once there were two major Trek editors, now there was one: Margaret Clark. Then, about a year later, SHE was laid off too, leading to the Trek books being edited by someone new without prior experience with the line, Jaime Costas. Then, the Abramsverse books were cancelled...and then Jaime Costas went on maternity leave, to boot!
Basically, from an editorial standpoint, just about everything that could've gone wrong has, recently, leading to a few books being delayed from last year to this year, then this year's releases getting reduced...then four of them cancelled...then next year's releases getting reduced, too. Not much that anyone can do about it though.
