The thing which I think will be interesting, even though it is a stupid kids game is that the hook on the ball. You can't just do a normal hook action bowling style and the ball hooks, you will miss your target all together. How I reckon they will work around this is (i'm a lefty) so you would move to the left and have to adjust the amount of hook you want, prior to bowling the ball.
Then if you can bowl it dead straight, from the left, and the hook will come in for you at the end. Cos it will be boring, just bowling straight balls all the time, but I'm pretty sure this is the only way to add hook in the game. The controller doesn't mimic your action, it only controls the movement of the controller. Be damn good if they make something decent and more realistic, than this kids garbage. But it's bowling, so...
