This chart shows the interchangeable lens camera sales in the last quarter of 2011, from CIPA. The dark blue ones are the mirrorless and the light blue for the DSLRs.
According to CIPA the mirrorless interchangeable camera sales is expected to reach 5 million units this year, more than two times for the year 2010; a rapid growing market (actually the fastest growing branch in photographic industry.)
The trend in Japan has always been decisive for the rest of the countries, at least for being a reliable indicator for "what's going to happen two years from now". This trend is indicative for what's being cooked now.. Probably in two years we will observe the 50% share of the mirrorless all over the world.
I think we are going to see some very interesting cameras in the oncoming Photokina in September, especially some models to interest us rangefinder users. I will not be surprised if Canon and Nikon had decided to "break their silence" to get their share in this 50% market to reach some 5 million cameras this year.
FYI, 5 million was the total sales of interchangeable lens digital cameras in 1999..
