When anybody says that all remakes are garbage, I tell them to hold my beer while I pop in John Carpenter's The Thing.
You are correct, Denis Villeneuve is currently working on Dune. The last thing I read was that he's splitting the first novel into two films. Right out of the gate, I think that's great. The books are so rich with history, world-building, and character development that to try and water it down will only poison the entire project. I do have a nostalgic soft spot for David Lynch's Dune from 1984 but I do see all of its flaws. Dune done properly would be a turning point in science fiction cinema.
