But I think it'll be Gatiss because - criticize all you want - they have so far been picking showrunners with longstanding connections with the series: RTD was a lifelong fan who wrote a Virgin New Adventures novel; Moffat likewise except he wrote short stories for Decalog as well as the well-received Curse of Fatal Death spoof in the 90s; Gatiss not only is a Doctor Who novelist of longstanding, but he was also (alongside Nicholas Briggs, Bill Baggs and Keith Barnfather) one of the producers/writers/directors who kept Doctor Who-related productions alive during the 1990s through his involvement with spin-offs such as PROBE.
