Here is the lowdown from pr:
CROSS GAME is a moving coming-of-age drama that is heartfelt and true and flows delightfully with a light and amusing touch. The series centers around a boy named Ko, the family of four sisters who live down the street, and their shared passion for the sport of baseball.
I haven't watched this series yet. But I'm guessing, like other baseball anime, one game is slowly dragged out over a couple of episodes. In that case, a dvd pack is so much better than waiting for weekly streaming updates. But, we shall see.
