No way, did they really say that?
Yes, they said it in the Q&A panel referring to high end legendaries specifically.

Trading became the easiest and fastest way to get items and we wanted to change that. We still see value in trading and want to keep it in the game, but we still haven't finalized it. Maybe the top tier of Legendaries will become account bound and also high level gems. We're still thinking about it.
Someone on reddit said they were talking to Wyatt about it and they didn't want the game to turn into pay to win on the black market instead. So, they're making all the most desirable stuff self-found only.
There's quite a bit of backlash on it. Personally I think it makes sense for what they're trying to achieve. It's inconsistent to remove the AH but leave item trading in the game.
I just hope they at least implement something where you can give the item to group members who were there when it dropped.
