The D500 is not a good comparison IMO. It's targetted at a different market than the 5DIV. It's supposed to be the best crop body for the sort of things the D5 is good at - sports, journalism and other fast paced uses where frame rate and super AF is king. Its natural competitor is the 7D2, not the 5D3 or 5D4.
3 seconds worth of buffer isn't all that bad for a jack of all trades camera like the 5D4 and I suspect only those who try to make it do the job of a 1DX2 or 7D2 are going to fill the buffer.
No question though that it'd be nice if Canon had spent a couple of extra Yen on buffer memory and card slots (why not use the same slots as the 1DX2? previously the 5D2 and 5D3 had the same slots as the 1D of the time) to push the camera a little beyond what is currently on the market rather than just about matching current competitors
That's true, but I was using it as an example of an extreme amount of buffer (challenging the D5 and 1Dx2) but priced way under the 5D4. I.e. it's not a case that it needs D5 or 1Dx2 money to get you that sort of internal RAM for a deep buffer - 50 shots on the D500 would have looked good; 200 is incredible. Plus, the 7D2 (intended for similar things as the D500/D5/1Dx2) only has room for 31 shots.
I guess it may be a Canon philosophy to go for a ~3 second buffer unless it's a 1D model (if you look across Canon's range, almost all the bodies have a RAW buffer depth something close to 3 seconds at the camera's maximum fps).
I'd be moderately surprised if the 5D4 didn't have enough internal RAM to allow for a bigger buffer depth (so it'll be an arbitrary firmware restriction); and if it doesn't, they certainly won't have saved much from the build price by compromising on slightly smaller capacity parts.
