1. Irrelevant - lots of movie tie ins on iOS. All consoles are locked down by their manufacturers.
2. Really? The sheer volume of games on mobiles would seem to contradict that statement. Infact there are probably more games on iOS/Android than have ever been released on any Sony or Nintendo handheld barring maybe the gameboy.
3. Meh - your only point with any credibilty - but still feeble. Even then poor controls have not stopped 3D shooters becoming one of the best sellers on the consoles in spite of the inferiority of control pads to Mouse/Keyboard.
I think what you meant to say way there will be always those who want a dedicated portable gaming device however a lot of casual gamers who want to waste 10-15 mins at a time would still find a phone suffices.
