Oh THAT'S what the hoopla is about? Don't answer that if it is and you got the NDA lol obviously, but I saw a couple of other oblique references to "D&D digital" from people talking about this on other parts of the net.
I didn't get the video, but I've been predicting WotC doing their own digital offering for quite a while now. It would also explain why the DNDBeyond people were so weirdly demoralized for the last few months, if they had some idea that was coming, and why a bunch of the more "official" D&D people who worked at DNDBeyond jumped ship a few months back.
That said, I hope they've got some sort of program for people who are already using the other products - because I'm sure as heck not re-buying everything and I doubt my players will want to re-create their characters and so on. I was kind of hoping they'd just buy Beyond.
