Last night's 'Boardwalk Empire' finale "Margate Sands" was notably light on major character deaths, but certaily packed a lot of punch to wrap up the season. Still, with another year gone by in Atlantic City, what might be on deck for the fourth season? Will Nucky Thompson have another major villain to face? Are there any characters from last night's finale that didn't actually die after all? Will the booze and blood still flow?
