It's not impossible. Games frequently allow you to use the arrow keys to move around while using the mouse to change the view direction (or vice versa).
I know that; I've played FPSes with that control layout for thousands of hours. I said "while controlling your vehicle with both hands" which means, for example, with a steering wheel, a throttle+joystick, or a keyboard+mouse with the mouse controlling something besides camera angle.
It's time to look back to see what was predicted a year ago and how successfully it was.
But even more, it's time for the fresh predictions for the following year, 2014.
