Not only the XQ2, but also the Fujifilm X-A2 (with new 16-50 lens) could be announced tomorrow. Although the rumor comes from a 100% anonymous source, I can well imagine that Fujifilm will announce both cameras together. (btw, thanks for sharing)
There will be a live blogging here on FR. I don’t know the time, but usually Fujiflm announces new gear around midnight New York time (6 AM in Paris).
