I don't plan to play 5e (I'm happy with my edition), and so I doubt I will buy any 5e books.
There's a good chance that many of the campaign setting material will be edition-neutral similar to the last few "4e" books that were printed. That's not settled yet, so we don't know for sure. Might tempt you to pick up some of the campaign setting stuff at least.
