I would be surprised if they do not eventually release the books as PDFs. When they pulled the PDFs back in 2009, I fully expected them to change their mind. We don't know what they have planned. I am just planning on being patient and see if they release them. I expect they will.
I hope so as well, but that will depend on what Hasbro will let them do. Hasbro is probably letting them post PDFs of older editions because it is out of print, it's income on non-production lines. 5e is still a production line, and Hasbro will want WotC to maximize profits.
Hopefully the criteria for getting legal 5e PDFs does not include, "No one pirates and everyone buys the first run." because our pirate friends have already ruined that.
