It's hard to see Anthony changing but in the movies it mentioned he was just like Micheal when he was growing up. Also in GF3 it seemed as though Anthony might have an interest in gambling in the scene, right before playing that song for his father. In GF4 Anthony should be included, in order to fully honor his uncle I would have Vincent send Anthony back to school to get his law degree. I would maybe have Anthony work at trying to get the family completely legitimate as a financial type advisor. But in his quest to legitimize the business he becomes unknowingly involved in an assassination attempt on Vincent.
