The RX1R release actually makes me curious. The Cybershot lineup was basically all Sony-Zeiss lenses, but Sony seemed to have been moving away from their cobranded Zony lenses for a while now with I think the last ILC Zony lens being the 35mm 1.4 released in 2015. RX10 died in 2017 and RX100 died in 2019, so its possible there's some contract Sony had with Zeiss for the entire Cybershot lineup, for a hypothetical example, stipulating all successor cybershots will be required to have a Zeiss lens + branding and also pay Zeiss a % of the sales. Otherwise I don't see why they're still using that ancient Zony 35mm f/2 lens which was even sharp enough for the 42MP sensor, not to even mention the 61MP one. Unfortunately no way to know an answer to this since even if the RX10/RX100 get renewed those cameras had actually incredible lenses for their form factors, so they probably don't need lens updates either ways.
