(SR4) One more APS-C model in the works (A75?)

One of my top sources confirmed that Sony has the plan to release one more APS-C model. It will be a new A7x (probably A75?). Two new (not yet trusted!) and one external sources said that the model will be on top of that [shoplink 8461]Sony A77[/shoplink]! And that’s actually a huge surprise. In what can the A7x be better than the A77? The model is definitely translucent and I guess that it will have less Mega-pixels and a much higher ISO range (+ more fps). I hope to get some specs about the camera soon!

P.S.: An external source at Sonyuserforum.de was at a presentation from Sony. They showed a pyramid with the A35, A55, A65 and A77. And the space on the top of the pyramid was empty. That is where the new A7x will be placed.

Reminder (SR = Sonyrumor):

SR3=50% chance it is correct
