There is now a mini-DTX AM4 board (ASUS)!
Example case:
You can see there is still space for two 2.5" drives.
The video shows a mini-ITX board, but mini-DTX would also fit.
It would seem that while the riser extension is used with mini-ITX, this AM4 board would do without it (because the GPU goes in the second slot).

I know Threadripper 3 needs more power, but I don't see why the socket could not be backward compatible.
Cause additional power is needed, so more pins are assigned to it. The existing ones are not enougo to feed these beasts.
Same socket, same pin count, different pin assignment. Therefore, no compatibility exists.
Too bad, but required for the more power hungry TR3.

On sTRX4, lots of pins that were previously unused by the TR4 socket have been enabled. The pin count is still 4094 for the socket itself for the SP3 socket but the revised naming should be considered here. The sTRX4 SP3 socket has more pins enabled than the TR4 SP3 socket.

Almost all pins are the same, except that some pins and two i/o data pins with unknown features remain surplus in TR4.
Could it be actually backwards compatible, just not enabled?On sTRX4, lots of pins that were previously unused by the TR4 socket have been enabled.

processors on both sides are incompatible because AMD has prevented them from booting through ID pin recognition.
In other words, if backward compatibility and scaling are needed, AMD will just put a ticket like TR4v2 and use surplus pins to make it closer to SP3.
Apparent confirmation that it would not really make sense to “upgrade” from Phenom II X6 to FX-81xx:

It would still be OK to replace an X6 on AM3+ so that this can be used to upgrade an AM2+ system.
The FX could be needed for software compatibility.

Slight performance bump at the same power if reusing the X6 for something else:
