Perhaps more telling would be Abrams NOT backing Orci. That could spell doom for Bad Robot as we know it, yes?
No, because Orci doesn't work for Bad Robot anymore. Five years ago, he and Kurtzman founded their own production company, K/O Paper Products, which was a production partner with Bad Robot on Into Darkness. Bad Robot basically equals J.J. Abrams and Bryan Burk. K/O has done a bunch of stuff that Abrams had nothing to do with, including Hawaii Five-0, Transformers: Prime, Cowboys and Aliens, Sleepy Hollow, Ender's Game, and possibly The Amazing Spider-Man 2, which Kurtzman & Orci cowrote. (Wikipedia lists that as a K/O Paper Products credit, but IMDb doesn't.)
These days, most executive producers have their own production companies, which I think are basically the producers themselves and their immediate staffs. So lots of shows and films are joint productions between multiple companies, which really just means multiple producers working together on a project. For instance, House M.D. was a co-production of Heel & Toe Films (Paul Attanasio & Katie Jacobs), Bad Hat Harry Productions (Bryan Singer), and Shore Z Productions (David Shore) along with NBC Universal Television. The more high-ranking producers on a show, the more vanity cards you'll see in its end credits.
