Disregard that last post, I did it better. This one also lets you compare vertical and horizontal spacing.

For those having a hard time with my stupid-ass choice of colors...
Wii U: 7 transverse, 29 longitudinal. Length ~29.83
PS3: 22 transverse, 14 longitudinal. Length ~26.07
360: 21 transverse, 15 longitudinal. Length ~25.81[/QUOTE]
Another thing to thing about with this besides just how far apart the analog stick and buttons are is where your hand is, specifically your thumb. with the traditional controllers you're reaching across the controller to get to the right analog stick. However with the Wii U controller both the stick and buttons are right there, there is no reaching across the controller with your thumb.
I think this could prove to be very comfortable actually and an advantage in moving your thumb back and forth between the two.
