Good news, fans of 'Treme'! Well, half-good news anyway. While HBO's acclaimed post-Katrina New Orleans drama 'Treme' kicked off its third season last night (going against the Emmys, ouch), HBO has officially renewed the series for a fourth season. Only, the fourth season is set to be the last, and to recieve a reduced order, at that! So exactly how many episodes will the reduced season be, and what are the creators saying?
