Sony just put this rather "mysterious" picture on their official site in China
Something alone the line of "1,500 days of anticipation" and then "Sony's BRAND NEW milestone about to be revealed" on the second line.
So far the speculations were revolving around the successor of their Z1000 or the legendary R10, either Z2000 or R100 but nothing concrete whatsoever. More likely to be closed back based on that picture with adjusted contrast.
I certainly hope this thread would be moved to the Summit-Fi section since Nomax was already briefly talking about something similar before
