To throw fuel on to this fire, I am considering switching camera systems from Canon to Sony.
From experience, I would advise against going Sony if you plan to make use of TTL in any combo.
Currently, there is zero TTL wireless RF trigger system that works with the newer Sony shotshoe. http://www.dpreview.com/forums/post/52459151
Also, there is NO flagship-level Sony speedlite that functions correctly (i.e. not overheat). http://community.sony.com/t5/Alpha-SLT-DSLR-Cameras/HVL-F60M-Flash-Overheating-Unusable/td-p/139177
In addition, Sony's newer shotshoe is not exactly standard, even for non-TTL firing. For example, my Yongnuo RF603 and Yongnuo 622c cannot be fired by Sony even in simple non-TTL trigger mode. I believe RF602 should work, but I would double check that Cyber Commander works with Sony hotshoe.
