I am endlessly thankful for the Arduino project as it was one of the major gateways to programming for me, but at the same time, I bought an Arduino R4 and have barely even used it. ESP32, Raspberry Pi, and even 8 bit Atmel chips get way more attention from me. I'm guessing that Renesas chip on the R4 won't be getting too much attention anymore.

And if you poke a bit around, not even that was really of their own making: http://arduinohistory.github.io/ . There also has been some discussion about that here on HN, e.g. https://news.ycombinator.com/item?id=46009209, which was less than a month ago.
