Sony China wrote this message on Weibo: “which RX camera do you expect?”. This confirms a new RX camera will be announced within 24 hours. When the 35F1.8 and A7R4 were announced they posted the same kind of teaser 24 hours before the official launch!
UPDATE: This time Sony China was well ahead of the announcement. It will take 72 hours instead of the usual 24hours and then we will get the new RX100VII.
