Try as I might, I missed that hustle IS coming back for a fifth season. Thanks Spec Odyssey for the note. See the press release here. Get your DVRs ready.
In my defense, I read from several sources that the series was cancelled.
From Wiki, the all-knowing source of all things*
Following much media speculation, including reports of the programme being cancelled and a motion picture spin-off, the BBC announced on 12 June 2008 that Hustle had been recommissioned for a fifth series. Adrian Lester will return, alongside Robert Glenister and Robert Vaughn, although Marc Warren and Jaime Murray will not appear.
The fifth series has been referred to as a "relaunch" by lead director James Strong and will feature Matt Di Angelo, Bill Bailey and Patrick Bergin as guest stars.
Even futoncritic is confused, calling the show canceled.
Okay, enough defending. That's the most recent scoop.
