It will fall until a PTR hits, or the next patch notes are posted.
A lot of people are just selling items and gold right now, and not playing. Waiting for the next patch, or any news on whats coming next and why. The same thing happens every patch cycle. There are a ton of people who only play D3 for a month or so after a patch, then lose interest and stop.
Partly because they are impatient, but mostly because Blizzard can't seem to figure out a system that holds our attention for longer.
