Have you seen the latest Sony tech rumor? Three sensors and ISO 918,200.

And the interview with the Sony exec?

And today's rumor - The NEX-7 (higher specced NEX), A77 (60D/D7000 level SLT) and a replacement for the A55 already!

The only reason that I can think of to replace the A55 is that they cannot make the sensors fast enough to supply it, the A580 and D7000.

Only rumors, but Sony is a fun place to be right now.

Btw - also a rumor about a Nikon mirrorless.
