Evercade
and I'm pretty excited about it!
(Disclaimer: Neither the YouTube nor the Evercade ppl asked or paid me for any endorsements of any kind )
Evercade's site says they are set to launch on April 9th 2020 in just 3 months from now. Are you going to get one?
Also; since I used to develop video games in DX Studio for windows - I am considering developing a video game of my own for their console as a Indie-Developer. I love this idea and maybe making a open source toolkit on GitHub but I'll have to wait and see if down the line some time there is a way for me to go for it.
I have left comments open here, please feel free to let me know if there are any 2D kinds of game styles you would like to see developed for a console like this.
