[Also, even Abrams was disappointed with the video game, so it should be taken as a learning experience not as a fatal blow.
Which I refuse to believe. Abrams has total creative authority over the Abramsverse, and has delayed the releases of comics and the YA novels because they hadn't yet been approved by him. If he felt the video game was disappointing, he could have prevented its release.
Based upon what has he delayed YA novels and comics? Because the comics continue on, and the novels are held not under his distribution rights.
Abrams does not have total creative authority, because distribution is controlled by different companies. The films are one part, and the TV, books and other materials are another part. If I recall correctly, Paramount has the freedom to make and distribute films, but CBS controls the rest of the distribution.
It is not that simple at all.
It was mentioned one of the YA novels missed it release date because Pocket Books hadn't received approval from Bad Robot. Indeed, the comics all get signed off by Orci, he even gets a credit in them because of that. And then there's the fact that Pocket's Prime Universe novel continuity is at the moment not allowed to touch the destruction of Romulus because Bad Robot doesn't want them touching anything from their movies. Bad Robot and by extension Abrams has full creative control over anything related the Abramsverse, the proof is out there.
