We have no such plans in the works. The issue is each camera manufacturer has its own protocols for TTL communication, and we would need to develop a system for each camera system (well...at least two). This also means we would have to licence or reverse engineer each of them, and that would be expensive either way. (look at a Nikon SB-900 price tag, and an Einstein price tag, pretty close but a lot more power with the Einstein) Plus, if we reverse engineered it, there are no guarantees it would work with future models. Additionally, with the way TTL flash works on digital cameras, with a pre-flash, I cannot say with any certainty if that would work reliably in the more powerful studio flashes (Einstein would have the best chance).
That being said, manual flash has the advantage of better consistency from shot to shot, where TTL can vary (and vary widely) based on what the camera sees, and its metering mode.
