There is a post over on sonyalpharumors.com speculating about the rumored Sony A5:
Lots of folks think it might be an RF-type body like the A6xxx series with a FF sensor at a price competitive with the RF and the Z5. I was reading the comments (because it makes me feel better about myself) and I came across a guy who said “all I want is the A7 II with updated innards”. It took all my self-control not to point out that was the A7 III.
