We don't know the outcome of anything in the Abrams timeline because it's a new reality we've never explored before. That was the point of creating the new timeline, so that nothing is a foregone conclusion.
A live action series is almost certainly going to be set in the Abrams timeline if for no other reason than to take advantage of actors like Quinto and Cho who would be likely to do TV cameos and give the show a PR boost. Even if that's the only way in which the universe is IDed, it will be enough.
CBS is not going to ignore the advantage if doing movie actor cameos. A new series will have a hard enough time as it is being a success, given the niche audience/big budget problem that all space opera series face. They'll need to try every trick in the book to make it succeed.
