I don't recall that Ricoh Imaging has indicated any firm date for an announcement. My understanding from their recent video statements is that they have been non-committal as to a specific date.
It may be recalled that in their first video published on
15 May 2020, the head of the new camera development, Wakashiro-san, indicated that "We have some concerns about factors such as delayed delivery from suppliers [owing to the pandemic]. But our factory managers have assured us that they will do everything possible to prevent any delay. Despite all the difficulties, I still believe we can make it happen [i.e., launch in 2020].
The head of Marketing, Kawauchi-san, summarized the status with "You can expect the arrival of the new APS-C format SLR flagship by the end of this year [2020]."
I don't think that Ricoh Imaging has provided any other indication of the timeline.
