Aka to Blue: Type R

Aka to Blue is a new shmup created by Tanoshimasu, a company where a lot of members are old CAVE. They started off with a mobile version and recently they announced a Switch port.

But how cool it is, they now also announced an Arcade version!

It will run on some new arcade platform called EXA Arcade hardware. It is PC-based, but with some custom components, such as an IO-board. Probably to get the input lag to the absolute lowest possible.
Games run both in 4:3 31kHz and 16:9 720p modus, which is pretty interesting choice. This allows existing cabinets to also run the hardware.

To get an impression, here is the Switch gameplay:
