Read my comment more closely. My point was that SLT is already a big step towards mirrorless and alpha will be completely mirrorless in the next refresh. This will give you possibilities that haven't before been possible. As for my example the D7100 you mention has the same 24MP sensor of the A77 and yet can only do 6fps. The point was that a 900$ camera could best a 6000$ one on dimensions that are very important to professional users like fps because of mirrorless technology. Mirrorless will give you some things only the very high-end could do before (or even the high-end couldn't do) at entry-level prices, that's textbook Innovators Dilemma.
