Particularly when it comes to series as poignantly dramatic as HBO's 'Boardwalk Empire,' it's helpful for the creative team to have an endpoint to work with.  Some series like 'Dexter' continue well past their prime, but the best know when to cash in their chips.  'Boardwalk Empire' in particular may only be going into its third season this fall, but how much longer do the crew think Nucky Johnson has to play his luck?

Boardwalk Empire may already have an endpoint in mind, according to show-runner Terence Winter.  The director recently spoke at the Banff World Media Festival in Alberta, Canada, wherein he laid out how long he'd ideally like to see his prohibition-era gangster drama run.  Says Winter:

God willing we could run six years that would be wonderful for me. But I take it one season at a time. It would be terrific.

As the show heads into its third season this fall, that would put the final season of 'Boardwalk Empire' squarely in 2015, provided it keeps its usual schedule.  Six seasons would also put 'Boardwalk Empire' on par with 'The Sopranos,' for which Terence Winter wrote prior to creating the Steve Buscemi gangster drama.

A number of questions remain over how 'Boardwalk Empire' will move on through season 3 after - SPOILER ALERT - season 2 finale "To the Lost" saw the death of Buscemi's fellow series lead Michael Pitt, playing Jimmy Darmody.  According to reports, ‘Boardwalk Empire’ season 3 will open some fifteen months after the events of ‘To the Lost,” landing on New Year’s Eve 1922-1923.

What say you?  Do you think four more seasons of 'Boardwalk Empire' would be enough?  How long would you like to see the series last  Sound off in the comments below!
