From today's NY Post:

June 6, 2005 -- WORD from the the set of "The Sopranos" is that a seventh and final season of the mob opera will be a short one — just six epsiodes.

The show is currently filming season six for debut sometime in March.

David Chase, the show's creator, at first said this would be the series' final season — but in the past few weeks, he has said he might do one more season.

Chase is considering "tacking on an additional six or so episodes to the shooting schedule" and doing a shortened seventh season, TVGuide.com reports.

That could mean there won't be the long break between seasons (this last hiatus was nearly two years) that has become something of a trademark for "The Sopranos." Instead, seasons six and seven would be separated by just a few months.
