Never until they stop finding new ways to convince people they need new GPU/monitors
I have been waiting for years for them to stop adding sparkly graphics and start making games more fun. I starting to think I will never see it in my life time. Although if we can have another
ET moment and games industry has to restart again, maybe we get some good games then. But if the fail game is released by Bethesda, stupid modders would fix it and it wouldn't cause a cataclysm... that would be a shame.
People buy broken games now, so I guess ET wouldn't be enough. They boiled that frog slow enough that now people still pre order broken games. The ET like event would have to be an amazing fail to bring down industry again.
