On paper, Rian would seem the obvious next step, considering vs. Feige he’s been developing for years now and his is a trilogy, plus he doesn’t have any other commitments. On the other hand, the Fiege addition is recent and there really haven’t been any updates on Rian’s films besides “still working on it.” I guess it’s impossible for us to know with the incredibly little information we have.
All I’ll say is this: potential bullet dodged.
