The sensor might able to handle it, but can the DIGIC X handle it? We can't know where the bottleneck is before we see different DIGIC/sensor combinations.The argument is good though. If the R5 could read and downscale the entire sensor 120 times per second, it would have 8K RAW 120p mode. Since it doesn't, 4K 120p can't be based on the full sensor resolution. So it's skipped, cropped or binned.
Personally, I think it's likely that the the full sensor readout tops out at 60-ish fps, but it could very well be able to do 90fps and the DIGIC X tops out at 70fps. Or the reverse.
Since we can't actually verify it, it's not a fact.That's less speculation than simply a fact. [..]
