That big shift will have to happen first. I don't see them ever making their own registry unless 99.99% of people are using yarn and are having a lot of problems with the current npm registry. While I see a lot of people using yarn, I'm not sure about 99.99% and I think npm's registry itself is pretty good.
So I don't think interests will ever align to create a new registry. Nobody wants to do that. That would have serious consquences for the JS community and would take years to recover, in my opinion.
