Here's a concept we can't make real but we can demonstrate on film:
Gun aiming only moves the crosshair on the screen and
touchpad aiming turns the view in the same way a mouse does.
Rationale:This requires no compromising in producing the next version of CoD because you can just switch off the gun aiming feature from the game and you're back to the typical mouse+keyboard control. Gun aiming is extra hardcore because it gives the gamer one more degree of freedom in aiming. I'm sure this can be at least as accurate as aiming with a mouse. More immersion, more control, more hardcore and only available with the Warlord on a PC.
