That may change batting dramatically. I think it's easier to hit the ball with the sweet spot of the bat in MLB Power Pros because the hitter's flyin' all around the box. If he stays planted in one place, that could make it a little more difficult, most notably with inside pitches.

If you notice in the videos, you can see the batters quickly shifting in the box as they swing, closing their stance to reach pitches on the outer half. It's much more realistic that way. I think the only thing it will change is now you wont have the ability to get beaned on any inside breaking ball.
