Since they have a contract for three films, I doubt it.
They will likely "mutually agree to go a different direction". It happens all the time.
Do you really believe that Abrams will go directly from Star Wars back to Star Trek in May 2015?
I certainly don't.
That's nice, but you really don't have a clue what you're talking about here.
Do you have a list of those at Bad Robot, other than Abrams, who are "going to Star Wars?"
Bad Robot will produce a Star Trek film for Paramount to be released in 2016. It's that simple.
