My glass-ball reading...
This is the video-centric camera landscape in FF now:
There are a few 8k 60p cameras, with acceptable-but-not-amazing readout speeds, Z9, Z8, R1, R5ii, A1 (I think 8k30p)
-6k with high readout speed A9iii, R3 and Z6iii.
-Pure 4k are ZVE1, FX3 and A7S3. only they do all-pixel 4k120p, even though it seems they actually read only some of the pixels because the sensor is a binned A1 sensor, hence the 4k120p is not super sharp in any of the cameras (still pretty good though).
The dynamic range, aka color IQ, is from best to worst A7S3/ZVE1/FX3, Z8-9, A1, R1-5 (to be confirmed), Z6iii, A9iii. These last ones seem to be about 2 stops worse (base ISO) than leading (slow readout such as A7R3-A73-Z6ii-S5ii-etc) sensors, also at MFT OM1 level, worse than a G9ii (at those particular conditions).
Most of them offer some type of raw video. Sometimes as "added feature", sometimes because the processing power cannot work into H.264 or H.265 file versions.
All of them offer "HQ" 4k, with oversampling. Many-most of them overheat in those conditions, I think exception R3 and FX3, and others with fan accessory.
The Canon and Sony offer excellent AF, the newer Nikon seem to have caught up. Differences now are more in detail, like subject detection and selection, and in which modes which AF works. All have some weird AF quirks in some specific conditions, but marginal.
Battery life is mostly OK, good in Sony and the large gripped cameras (R1-3-Z9).
Overheating is a concern in most of them, except probably Z9, A7S3 and FX3.
...
So what can Lumix do?
I would say, first thing, to use a Dynamic Range Boost sensor, like GH7. This will let them use a low gain, clean low ISO (probably like Nikon, so base ISO 64 in photos), and combine it with a high gain shadow gain circuit. They would offer Arri level DR. If they also offer Arri Log and Apple Prores Raw...
I think 24 MPX is enough, even 22 if necessary.
Different readout modes with and without DR boost for different requirements of rolling shutter and DR.
A CINE version with only DfD focus, no PD pixels, no IBIS.
GH7 body.
Expand to other raw format(s) internally that Davinci (the de-facto winner of the NLE wars) can use natively.
2 fast cards or 1 card + SSD dual recording.
Open gate in all possible formats.
Proxy in MP4Lite format.
...
With those features (and no overheating and great IBIS etc that they do well already), I see them winning back lots of market share in the professional video space.
That camera can easily be at 4k price and still be a bargain.
