After the split from scribes Roberto Orci and Alex Kutzman a few weeks ago it seems Rob Orci has already moved onto bigger and better things according to Deadline. While Alex Kutzman is focusing on directing Venom over at Sony, Paramount will end up going with Roberto Orci to helm Star Trek 3 in his directorial debut.
He is the clear choice by both Paramount and JJ Abrams to take over the franchise in Abrams absence. While he hasn't officially signed he is indeed the frontrunner. Roberto Orci credits including screenwriting the first two Star Treks as well as Transformers, Fringe and the recent The Amazing Spider-Man 2.
Star Trek 3 is expected to come out in 2016 but subject to change
