Doubt it, gaming industries to mature and proliferated to be eradicated by a few greedy companies, sure gamers may become disenchanted with content and the industry might erode a little but there will always be indie developers (now that content distribution is superior to the 80's) and the rise of new developers (the gaming industry consists of qualified professionals now that will be forced to reenter the industry or face redundancy). In addition theres alot more competitivity in the industry than back in the 80's, greedy capitalisation isn't as feasible due to higher expectations.
Finally, dont forget there are still legitimate publishers out there, take CD Projekt Red's announcement of free DLC content and their quick response to community problems. Basically its only EA and Activision that are acquiring too much of the industry and abusing developers with their insane profit expectations and capitalisation tactics.
