A new rumor claims licensed SEGA hardware could return as a cartridge-based handheld aimed at 2D indie games instead of basic retro emulation.

(Apologies if this was posted already, but I searched and didn’t see anything.)

I think there’s definitely a niche market for a low specs/low price handheld for 2D retro-style games. Here’s hoping the rumor is true!
