I don't think anything is going to be decided until the end of 2012. I think this is the proposed idea at the current time.
From Greg Cummings Facebook page:
There has been alot of talk about a nonbreakout car class at the King. There are so many options its going to be hard to make everybody happy, and to be fair. What do you think of a spec type class? Handout Trinity locked motor, Handout battery, set gear, no timing esc(blinky). 30.00 entry you draw for your battery, and motor. We will tech for voltage, battery and motor temp. If we do this we will start with 10 sets and more if it grows. So what do you think?
