Lol.
Joking aside the Sony lineup made sense, until the A1 came out.
A7 "entry level" all rounder - makes sense
A7R high res model - makes sense
A7S video model - makes sense for videographers
A9 - High performing sports model - makes sense.
A1 - High res high performance sports cam - Kind of made sense at the time but now I question where the A9 fits in.
If the rumoured A9iii is true then performance wise it needs to be at least on par, or surpass the A1 for it to be a meaningful upgrade over the A9ii but this will then likely take sales away from the A1, especially for sports togs who do not need hi res and would prefer the smaller files.
If the A1 is to run parallel to the A9 as a high res version of the A9 (similar to the A7 and A7R) then it's a heft premium just for a bit more res
If the A9iii is on the cards for me it's got to have the latest AF AI (or maybe a new version), better EVF, better LCD (included the new fangled vari-angle and tilt), lossless compression, and better slow shutter panning with the EVF, i.e. little to know slideshow effect. Oh, faster readout time too so the electronic shutter can be used with flash.
