@SupaPhly part of the reason could be that they are more responsive to FOREX fluctuations than MS or Valve. The other reason is that we are so small for Sony that they can't be bothered to match what happens on the other platforms.
If you have both consoles it allows you to price shop, i've picked up a few games this way.
Star Fox Zero turns the Wii U GamePad into the view from the cockpit of Fox McCloud's Arwing fighter. While the TV shows the perspective from behind the Arwing, players can also use the gyro sensors of the GamePad to intuitively and independently target enemies. Players can instantly switch between the Arwing and Landmaster tank with the press of a button, and the game also introduces a new helicopter-type vehicle.
