Sony recently released the RX1. A full frame sensored mirrorless camera and it seems many of the other manufacturers are looking at this move and we could see a whole plethora of these FF mirrorless cameras in the next 12 months or so. Certainly the RX1 is priced more than most entry/prosumer DSLR prices, but I reckon the next few years will be an interesting market place for these.
