I had to vote "D&D is dead to me" because I'm long off the hook with the edition by now, so I am unlikely to purchase any new book. But if I'm going to buy anything, it's definitely going to be settings books, because I'm done with players material until 7e (I don't play half editions, and apparently neither even-numbered ones), and on the adventures modules side I still have too many from previous editions I haven't run yet. But settings books are always quite nice to read, even if I don't use them in a game... now the SCAG was very poor IMHO so the precedents for FR books in 5e aren't exactly promising, but I'll always keep an eye open.
