Japan: Why all the big headed baseball games?

Tim Rogers from Next-Gen has done some "investigatory journalism" behind the popularity of big-headed baseball games in Japan. He argues that although games like Jikkyou Powerful Pro Baseball 13 can be fun, they represent "an unfortunate trend in design" due to their playful, yet non-realistic look. The reasoning seems to be that so long as Japanese developers struggle with uncanny valley, falling short of making a game look exactly like reality, Japanese gamers prefer the added "warmth" of cartoony, playable characters, at least in baseball games.
