Just saw a commercial for it. A quick internet search brought up this site:

Doesn't look anything like Billy. But then again, his RBI persona didn't look much like him either.
Tengen (though they don't really exist anymore) should be suing their ass. It's a blantant attempt to profit off the enormous successs of RBI. Then again, their marketing guys need to get canned, plenty of better RBI'ers to name a game after.
I personally would have went with Harry Spilman and the Giant Egg
