I agree, would like some more challenge with pitching. But it sounds like they are trying to get more realistic pitch counts, which could drain stamina leading to lower accuracy.
"There's now a stat for how many pitches a batter averages on a plate appearance. Basically, 2K11 knows if a batter tends to extend an at-bat by taking a lot of pitches (or fouling a lot of them off)"
This could make it more interesting and give each batter their own personality. We'll see.
