IGN has just posted their MLB 11 The Show preview. They talk about the new analog controls, balks and more control.
"The Show 11 features analog control for batting, pitching and fielding, which basically means every major mechanic in the game is controllable with the right analog stick. For batting, you'll pull back the right stick to begin the backswing and then push it forward to swing through a pitch. You can angle the stick to the left or the right to handle inside and outside pitches, while the game will automatically adjust to pitch height for you. To check swing, just let off the stick before pushing it all the way up.
Pitching works like a combination of batting and fielding. You'll still pick the pitch type with face buttons then use a cursor to adjust pitch location. Once you're ready to throw, you'll set and go into your windup by pulling back on the stick and then push it forward, either favoring the left of the right side of the plate to shade the pitch a little more. Setting before you pitch is more important in The Show 11. Sony has included balks for the first time in the series, so don't try to quick pitch with runners on base."
