There is a lot of use of ProTools in professional studios, but this is mostly for the special effects it allows, not for sound quality. These special effects soon fall out of fashion, and I don't think this trend will define studios permanently.
For a number of years, I'd been around the kind of people who financed movies and the kind of people who are there to make the deals for movies. But I'd always had this naive idea that everybody wants to make movies as good as they can be, which is stupid.
