NO IT IS NOT DYING!!! JUST GOING THROUGH ANOTHER CYCLE.
1977-1987 - Coleco and Maganvox are gone. Atari is still selling 2600&7800 and INTV is selling Intellivision III. Nintendo, Sega and NEC are all selling systems.
1988-1998 - 3DO, Atari, INTV, NEC, Phillips and my favorite the Action Max are gone. Nintendo, Sega and Sony are selling systems.
1999-2009 - Sega is gone from the console business. Microsoft, Nintendo and Sony are all selling the next gen-consoles.
2010-2020 - The big three(MNS) are all selling systems. Atari Flashblacks, Coleco, Intellivision Plug&Play's are on store shelves. Maybe one of the three will stumble but the demand is still around.
Every Cycle there is a loss. Maybe this one Atari, Coleco and Intellivision will leave again. Who knows? Just enjoy gaming time while you can.
One day old age problems will catch up and you will wish you hadn't wasted your time fretting over something that is out of your control.
