Yes. The second pilot screwed up royally. Of course we can wait a
year for the NTSB to come to that conclusion.

The fact that someone screwed up or didn't screw up isn't what takes all
the time to figure out in an aircraft accident. That part of it,
especially in an accident like this one, is usually solved fairly
quickly. To be quite frank, I'd be surprised to discover that the NTSB
didn't have the answer to this one as we speak.
What takes a bit of time is going into the P51 and warbird demonstration
communities and implementing the changes, education, and re-education
necessary to increase safety awareness generally.

The easy part can be the discovery that somebody made a mistake, or
"screwed up". The hard part is discovering WHY that someone made that
mistake or "screwed up", then finding a way to help prevent it from
happening again.
It's the WHY that takes the year; at least this has been my experience
dealing with aviation accidents, flight safety, and prevention.
