I would also snap two of these up, as a current A99 user I have been keeping an eye on the 7 series cameras and have a good friend who has gone that way (A7r, and now A7rII), so I have hands on experience with both, and still prefer the A99 type of camera. I just needs a refresh with all of the current goodies as it is now 3 years old. Yes drop the SLT as it really is a mirrorless camera in all but name, and the SLT was really a beam splitter for the AF which with the advances in on sensor tech is now redundant.
