As stated before in a quote it looks like the raspberry pi trading ltd rushed indeed releasing this board. Every day passing this 16nm lithography design (introduced 2016 - so 7 years old) it’s collecting dust. 
As a side note a RK3588(S) comes with a NPU integrated with 6 TOPS (50% more than a coral NPU) 
The Orange Pi 5 Plus even features 2xPCIe and 2.5G LAN 
The Price for a (available) Orange Pi 5 VS a (not available) Raspberry Pi 5 looks like to be in the same ball park while the later offers much less (CPU,GPU,NPU,Storage) 
And the “new” VideoCore 7 GPU from the Raspberry Pi 5 looks like a joke based on the limited information available
It looks like to have 12 (
) times lower performance than the Mali G610 found in the two year older RK3588 based SBC’s like the Orange Pi 5

Looks like the Raspberry 5 is easy 2 years late for the show
