Re: Abrams turns Star Wars because of his "loyalty" to Trek
His loyalty to Trek could simply be down to them being a gainful source of happy employment. He doesn't have to have been a pre-existing fan to have developed an attachment to where he works.
Frankly I think it extends beyond the whole Trek/Wars argument entirely.
Abrams currently has a good working relationship with Paramount, which he's had since Mission Impossible 3. Cloverfield, Super 8? Paramount.
Making Star Trek films is only part of that relationship, although it's the one tentpole franchise he's attached to directing so it's not a small part.
