Yeah that's a brilliant idea remove single player from everything
Or do they mean that all future games will allow you to play the campaign mode multiplayer if you wish. (Like Fable III or Perfect Dark or Halo, or Gears), cause that's alright as long as I'm not saddled with a shitty AI controlled partner if I'm playing alone (if I'm playing alone I don't want a partner forced on me just for the sake of a multiplayer option)
But if we are talking about a future where all games require 2+ people, then that's just stupid
