Thanks for all of the replies guys, I like to hear some actual installs on stuff like this before I pull the trigger.
I emailed Holley tech support and asked them some questions. It seems at SEMA they unveiled a "new" Terminator which is essentially a Terminator throttle body with a Dominator ECU. Like Hugger67RSSS mentioned it will control 4L60E/4L80E transmissions which is what I am after. Tech Support said look for it first quarter of this year.
