I have shown my love for Dante Commentary tracks in the past. But, I didn't expect a reply from him (or perhaps his PA) until this arrived.
Regardless, it's a nice update on his Commentary schedule for the future:

I don't believe the Body Snatchers commentary will ever be released as the
movie has changed owners. Right now I'm concentrating on doing more TFH
commentaries, altho I am part of an upcoming Grand Theft Auto commentary
for Shout Factory. Thanx for asking.

So, sadly, no Snatchers commentary. However, it looks like Ron Howard's directorial debut will get the treatment. I believe Mr. Dante edited that film, like many Corman movies of that time.
