It does look like he's sticking around for Contender S2, so I'm hoping a few teams get added for S2 and that we see more of these pro guys that didn't get a spot have their chance.
I'm also assuming a crazy amount of turnover as teams that couldn't deliver restructure their squads. We could see some crazy things happening in 2018 if OWL and Overwatch are a relative success.
