Huh? That twitter doesn't mean anything. It would been a different story if he was raving about the costumes/designs and the footage that's already been shot.
I have no familiarity with Dune, but hopefully Denis and the producers recognize that it's going to need good pacing and action if it's going to be successful. If he frames it after Blade Runner 2049, which is a decent movie, it's going to flop.
Filming on the first Dune movie has been completed, is "in the can," and there's been a wrap party. Some actors are already working on other projects, and saying great things about how Denis Villeneuve ran the movie sets.
