I would be very surprised if there was an additional print run of the Tyranny of Dragons books. The focus of investment starting this month will be Elemental Evil.
The event is over and they're moving forward. There's no reason to expect continued print runs of the adventures and more than to expect reprinting of AP volumes from Paizo. It's not a core product, there's no reason to keep it continuously in print.
IF there's a lot of demand or it sells out quickly, they might do a second smaller print run. But continuously reprinting means eventually they'll have unsold copies, which is wasted money.
