It's not a new idea, they have plenty of experience at getting the hole lined up. Hunts did it with the original Turbo and some other bats i believe. There were also bats that were drilled and the hole filled with cork, though i think this is now banned. These holes may have run almost the length of the bat, whereas this new bat does not a full length hole.
The Turbo Revolutions hole doesn't run the full length of the bat, just through the area we would class as the middle. It is capped where it comes out the back of the cleft, this is almost unnoticeable based on the one i saw.
