"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"
When it talks about the gyro, it says players CAN also use it to independently fire at enemies, this being said, it looks like you will not be forced to use the gamepad's gyro to attack enemies, and it might also mean there is auto target. Hopefully, they include the gyro, auto target, and manual target to the game for the best expirence for all players
