That is a lot of Sony stuff…
Like Apple they strive to release unique and innovative products, but unlike Apple their balance is (at least for me) to much on the innovation side than on the refinement side.
The NEX System is great, but apart from taking it FF it would still needs a few more lenses (tele prime, good wide angle prime, fast zoom), faster AF (sensor problem?), better usability (menu structure, exposure compensation…), weather sealing and so on.
Keeping in mind that Sony is able to release a new camera body every 6 month but no major firmware update, they do not have the right balance.
I think the key part of such a device would be the integration with a smartphone to easily share pictures instantaneous. Wi-Fi is nice but I don‘t want to disconnect my iPhone to connect to my camera (at least with my NEX 6 I dislike this process a lot). Why not bluetooth? Why no clever dock/usb connector cable?
