You know, never is a long time. And while I can understand the desire to see pdf versions of their work for sale. Honestly, even classic novels go "out of print" on occasion. Demanding that *everything* be available in pdf before you'll buy a single product from them is pretty darned steep.
As far as I know,
everything was available before (as far as game publications...I'm not talking about novels...they can deal with Amazon and e-readers for that). If it wasn't everything, then it was pretty darned close. But, it probably is more accurate for me to say I want everything that was available before they pulled pdf's, to be available again,...and all products that came after that (all 4E pubs)...before I buy another WotC product.
That may seem unreasonable to some, and that's as fair an opinion as mine. But I won't reward WotC for behavior that I think is wrong.
My reasoning is, I don't ever
need another D&D product...I have all I'd ever need for a lifetime of playing - and then some (you can have my dice when you pry them from my cold, dead, uberpowerful Lich hands!

). I think that there are a very large amount of gamers who also feel they no longer
need new D&D products. I think that the loss of such a large amount of gamers as current paying customers shows that. However, I do believe that if they make a game that a large amount of gamers
want, then a large amount of gamers will buy it. That is if they aren't already voting with their feet and wallets because of other issues. For me, the pdf issue is paramount. I think they were 100% wrong in their reasoning for pulling them. And I think that whether intended or not, it was incredibly insulting to their fan base, and punishing their innocent fans...the majority of their fans...for the sins of a few. And that's just plain bad business. So I'm voting with my wallet.
Even if 5E isn't the game for me, I would buy at least the core books, and even occasional other products that strike my fancy, and most likely a DDI subscription...just as I did with 4E, which also wasn't my preferred game. But only if pdf's return first.
