In Wan’s words:

Based on this statement, Wan is playing it smart. His exact role in the potential movie is not set in stone yet, so he could be the director or the producer for all we know. With the projects he has on his plate at the moment, it’s highly debatable what role he could take.

It’s been twenty years since we’ve had a Mortal Kombat movie, and not a very good one, but based on these words of such a promising director, it’s possible Mortal Kombat fans may get the film they deserve.
