I would like to see an Atari arcade product. The 2600 has been done to death and the top Atari properties are best on arcade hardware.
The issue I see is those games require proper controllers and that gets expensive.
But I can't wait to see if they release another 2600 with Fun With Numbers and Basic Math.
But all joking aside, they should do a "final" flashback with proper paddle support and sd-card support. Essentially a modern VCS. Just re-release it every year.
