That might be an issue though, if the developers aren't careful about it.
Remember, the Wii U will likely be able to play all Wii U games on the tablet screen alone. Now, I don't believe it will be a necessity (unlike the Wii where every game had to be Wii Remote usable), because Nintendo have said they want devs to feel flexible in what they do for the system.
That's why I haven't listed the touchscreen as any function for that CoD example. The screen will always display the same HUD values of that in other versions, minus controller specific tooltips.
While yes, the touchscreen can extend the button input versatility of a consoles makeup, developers need to understand that they can't just add everything to the touchscreen without thinking about it.
The only other thing I can think of that also works in that CoD example (in a way so that it doesn't compromise on HUD values, but so they don't have to do a motion gesture to knife) is to make that touchscreen a single function, in this case knifing. No matter where you'd touch that screen, it will knife, and so you can play the game separate from the TV, still have all functions and not have the HUD values disrupted
But even if you did this, you'd have to let go of the controller with a hand to touch the screen with your finger. That doesn't seem like the thing I would do, so the only other thing I can think of, without letting go, is to touch the screen with my runy, dribbly nose/chin. Not very practical, or hygienic, so motion gesture it probably will be.
I hope, for the sake of this system, that everyone doesn't go assuming that the touchscreen replaces all buttons. After all, simple is effective.
