A couple questions.

What is the meaning of R ? Arduino Uno R4 , but then there is Arduino Uno Rev 2

Last but not least Any idea why Rev 2 Wifi is way more expensive than the Uno R4 Wifi ?

2

R stands for Revision (as does Rev)

3

Because that is what Arduino decided to do in order to attract people to the new processor in the new processor in the Uno R4 WIFI and the Arduino R4 Minima.

There are separate sections on the forum to ask about the R4 Unos.
