Yes as global internet becomes both household, and fast. Most people will be drawn to the convenience of streaming games, whether it is on the phone, or on their tv. I think it's farther off then a lot of doomposters, and journalists like to think though. In many places in America, that aren't major cities, or on the coast, there is terrible to no cell reception, and slow to no internet at home.
When it happens, I will stop playing new games, and stick with old games.
