Not that obselence isn't a fact of life with all these camera lately
A SR4 level rumor has surfaced that the next iteration of the A mount cameras will sport a brand new EFV with an increase of resolution to 4mio dot.
How long before that appears in an A7RX?
Two new FF A mount SLTs coming in 2014 (SR4 rumor) ... including a high-end flagship model with a dual A/E mount ... flip a lever, remove the A mount, and you have an E mount. One FF may be as early as Spring (my bet is 36 meg with the new EVF) ... the other the end of 2014 (my bet is 50+ meg with the dual A/E mount, global shutter, and possibly an even higher res EVF).
The Sony "Cornucopia of Cameras" keeps spilling them out.
Hope they continue to keep prices in check so our wallets can keep up
