Interesting nugget... I have serial number 31000-1166 from Dave and is dated 8/17/20 with the 2 MHz label, and my other one here is 31000-1161 dated 7/22/20 and is labeled 2.5 MHz
So looks like they cut over just after 1160s, i'll have to set something up to compare them sometime

Mine has a serial number of 31000-1523 and is labelled as 2MHz. Dated same as yours 2020-08-17.

All my units are 2MHz.
They might have re-labled old stock units. I don't believe there is any electrical change, they just decided to be more conversative with the spec based on production testing.

My 2.5 Mhz version got the S/N 31000-1044 and is dated from 29.05.2020

I recently got the CP2100A and I did a review & teardown on my yt channel I will link the video below the text. I also published some images from the teardown here so if you are interested in taking a closer look to identify any differences between the A and B variant, these should help. From what I could tell the markings on the sensor is 8877 which is the same as what you guys have on the 2MHz B variant, right? BTW if you are looking to get the CP2100A 800KHz there is a discount code mentioned on my video, you could use that to get a better deal.
Algasman:
After following the discussions and trying to decide if I should go with the A or B version, I decided for the economic more bang for the buck A-Version.
Last week I got it delivered so I wanted to check the performance myself. The results are almost too good to be true, so I would like to know if you agree with my test setup.
SDG1032X as source, feeding a BNC-connector through 5 loops on the current probe clamp into 3x150 Ohms. SDS1204X-E Channel 1 Voltage of 50 Ohm load resistor, 10x Probe, Channel 4 CP2100A 2x (because of the 5 turn coil)
During measurement, I maintained 2,50V RMS over the load resistor, and measured the current as RMS (nominal 50mA)
This picture shows the voltage and current @800kHz, the nominal bandwidth of the CP2100A.
To me this looks much better than the specs, is my setup suitable for bandwidth measurement?
