Bullshit. This is wrong for one simple reason: people like single player games. This is not something that is going to change, no matter how much high-up businessmen in the industry want it to. Therefore single player games are not going to die out, only fluctuate steadily like everything else: as they stop getting made, the few that are made will sell more. Companies will see this and make their own single player games, which will begin to make less in turn until they gradually stop making them again, at which point the few that are made will own the market again and make lots of money, meaning more will be made, etc etc.
No, the reason this argument keeps being brought up isn't because it's true. It's because it's what publishers desperately want to happen because single player games are prone to pirates about a million times more than multiplayer games. ...That's it. That is literally the only reason. Just look through this thread to see how many people hate this idea and you'll realize that something that lots and lots of people enjoy is not going to stop being made.
