we come to the era which is similar trend during the last time when Console start to replacing Arcade.
TV might replace Movie Theater...

these are all game changer. But console will not dead so easily. Just take a look on Movie Theater, when people though the theater might dead when TV was invented. but is still alive today...

I found a interesting research from here, if you can spare sometime watching it.. is very informative..
