I think we already know that Sarek wasn't the greatest of parents, at least as far as his prejudice against Starfleet and Spock's career choice was concerned.We do know they should be able use Spock though. I mean the big add was about the show being
10 years before Kirk,Spock and the Enterprise." I do wonder about Sybok. Who has the rights to that character, I wonder. Who knows maybe she was one of the reasons he embraced emotion which got him kicked out. Which does bring up the issue of Sarek not being the greatest of parents and I hope the remember that for the show.
