This new board from Arduino seems like an interesting toy. It's a combination of ARM Cortex M0 and FPGA Intel (Altera) Cyclone 10CL016 (16K LE) with 8MB of SDRAM and Micro HDMI port on a small board, plus pins to connect peripherals (SD card and joysticks - possibly NES style
could be used as they require only 3 data lines, see uzebox project for reference). The price also seems to be reasonable (50Eur).
I wonder whether a mini version of MiST could be be achieved, sporting some smaller cores, 8 bit micros and old arcades.
