Chalk this up as a big rumor directly from a source acquired from YouTuber Spawn Wave, but SNK might be joining the endless crew of companies putting out "mini" systems with pre-selected games.
Allegedly the console is set up like a fully sufficient arcade machine with an arcade stick and authentic buttons, but also has a gamepad port on the side, as well as HDMI out (read: you can play it on your TV too instead of the tiny screen). The source claims it'll sport 40 games, the full list of which you can find below.
All of this will possibly go for roughly $100. So far the only official lead is SNK confirming an all-in-one-system of some sort -- so we'll get more info directly from the company at some point. For now, this is looking pretty sweet.
