I emailed Profoto last week about whether or not TTL support was coming to Sony or any other cameras besides Canon and Nikon. I just put money down on a D1 Studio 100/500/500 Kit and was considering the B1 kit down the line if TTL support came to Sony eventually. Apparently it's already under consideration for the next TTL controller after the Nikon one is finished. This of course isn't a guarantee that it's going to happen but it's nice to know that some of the professional standard companies are taking Sony a bit more seriously when it comes to accessories... especially in the realm of lighting.
Just thought there are a few people here that might like to know about the current state of it all.
