there are lots of ways it could be different he did mention the lens issue as well. so I'm guessing 2013 not this year since there are a number of needed lenses to drop the body on the market (and a clear roadmap on more)
But it is doable. given how deprived the company seems to have been in the last 18-24 months for R&D on lenses and anything else I am surprised they have got as much on the go as they have. I'm also impressed with how them seem to be trying to address it rapidly and build a line that is viable as quickly as possible. Every quote i read tells me the next 2 years are going to be the polar opposite of the last 4 from a release standpoint (and probably a marketing one as well)
Sony has FF Sr Clavius (and wasn't the a900 weather sealed mag alloy as well? so not unique. K mount it unique of course but i doubt that was the intent of the comment.
a digital LX in mirrorless form would be unique
