Announcement coming soon or is this camera never going to materialize?
DC is reporting the LX200 is coming to PK if you must grab something newer.
G1X III is not coming to PK, it's a 5D centric PK this year.
Now that said, it may be coming later this year, like my M5 supposedly is. XC15 is coming shortly too. Obviously there is another Canon announcement after PK for at least the confirmed XC15, which may or may not have a new powershot coming. And to that point, which Powershot gets an update? Dunno. Canon is very secretive as of late.
