There is a plan. Please read here.
The fact that there is a plan, however, does not mean that this will actually happen. The Twisted kernel has already been ported to Python 3, so you already use it in a way, but in fact all the code works in Python 3, the Twisted project needs volunteers with an active interest in porting things to Python 3, who will devote time and energy to doing this plan. If you plan to deploy Twisted on Python 3, we really need you to pick up a couple of the tickets mentioned in this plan and make corrections for them.
Thanks in advance!
