I am less polite than you when it comes to WotC. The truth is, it was just another cheap media buzz to keep people interested that they desperately want to buy their books,
but never actually do anything to garner to their interest.
FR rebooted? Ah, who cares? There's so much out for the setting that it's nearly unplayable on canonic terms. I don't think it's a bad setting, by any means,
but apart from stuff that was already out twenty years ago, I have ZERO interest in new books. There's so much to read out there that it's kind of arbitrary already.
As for 5e support for older settings, I think that seals the coffin. IF they had something THAT big to announce, they would have done it on Gencon.
I am happy that the back catalogue is going to be rereleased, though. Hopefully, that will keep our branch of the community open for a few years longer.
