As far as I can see it and how different youtubers described it, the product placement of the differet bodies is now as follows:
Lumix S1IIe
2.800€. Improved version of the S5IIx. Same 24MP sensor, but the rest better (body, AF, speed, processor, EVF, tilting screen etc.). More expensive than launch price of S5IIx to be able to offer both at different price levels. Ability to copy SD/CF card directly to SSD in future FW. User shall decide depending on budget and required tech.
Lumix S1II
3.500€. New 24 MP half-stacked sensor. Improved version of S1H and merger with S1. All features are better than with S1H and it is 800 USD cheaper than the S1H at launch. Same body as S1IIe and S1RII. optimized for video, best rolling shutter of all 3. Highspeed 10/70fps (m/e). Biggest buffer of all 3 (ca. 180 images), but not yet a sports camera. Ability to copy SD/CF card directly to SSD in future FW.
Lumix S1RII
3.600€. New BSI (non stacked) 44MP sensor. Replaces the S1R. In almost all features better than S1R and with some on par (i.e. EVF). AF etc. same as with S1II and S1IIe. Image quality for photography better than S1R and S1II. Not just resolution, also colours etc. Highspeed 10/40fps (m/e). Because of sensor and MP, rolling shutter risk with video and electronic shutter. Smaller buffer than S1II ("only" 70 images). Ability to copy SD/CF card directly to SSD in future FW.
The following 4 (old) bodies stay in the product line. Products now on all price levels for different target groups
S9 (street price 1.200€)
S5 (street price 999€),
S5II (street price 1.900€)
S5IIx (street price 2.200€)
Edit: I find the price gap between S5 (street price 999€) and S5II (street price 1.900€) too big. Maybe we'll get a surprise after all? Something for around 1.500€ with EVF?
