Will X-T5 video quality be worse than X-T3/4?

Based on the specs - it seems like the video quality of the X-T5 might actually be worse than the X-T4, and possibly even the X-T3.

The only option for over-sampled 4k requires a crop, whereas the 4 and 5 used the full sensor. Will it actually look worse than the older cameras?

I have no problem with the X-T5 not being a huge upgrade in terms of video capabilities, but having it actually get potentially worse is a bit weird...

Otherwise I would be happy enough to just get the X-T4 now, but I prefer the tilt screen

Odd perspective... you have two H cameras, and an economical S camera that meets your needs, and you really think it makes sense that those of us who shoot stills 90+% of the time should endlessly bend over backwards to meet video needs to our exclusion?

In any event, T5 has better IBIS, better EV, better screen, better AF tracking, almost certainly significantly better overall IQ for video (based on both processing and number of pixels), and higher battery rating (CIPA)... yet you think the video compromises elsewhere are greater. Not in real-world use - at least based on the stats and early impressions we've seen so far.

I think you misunderstand how video works. Yes, the X-T5 has a 40mp sensor, but this doesn't matter for video.

Full HD is 1080x1920 = roughly 2mp

4k is 3840x2160 = roughly 8.3mp

What normally happens is that the full sensor width gets used and then combined into 3840 pixels (oversampling). The X-T4 oversamples 6k footage into 4k. This yields sharper image quality (with other benefits).

The heat sink of the X-T5 seems to be too small for the sensor/cpu combination. So one only has the option between subsampled 4k (only using 3840 pixels, NOT the whole width of the sensor) or oversampled 4k with a 1.23x crop.

So yes, 4k video should look sharper on the X-T4 compared to the X-T5.

This is also the reason why cameras like the Sony A7S or FX3 only have 12mp sensors.

I never made any reference to the pixel density, nor the oversampling - so you're guessing that I don't get it. In reality, if you do a test, you will find that the various X-T cameras perform best in sharpness and lack of artifacts at 2k... but you are buying into the "my amp goes to 11" marketing gimmick.

We haven't been told the heat tolerance of the T5, so it is anyone's guess if it is better or worse than the T3 or T4. We do know (based on CIPA rating) that the T5 uses less energy, so likely generates less heat than the T4.... So, very possibly the T5 could outperform the T4 on that measure.

The other thing I should have mentioned is the lower ISO @ 125 yields greater DR and lower noise. This is especially beneficial for FLOG and FLOG 2 which rely on higher ISO (2x-3x), allowing for presumed lower noise - but again this is just a best guess based on specs for what is still a pre-production camera. But don't be surprised if it performs quite impressively - at least for shorter clips - which is what most stills shooters are going to want for the occasional video.
