Katherine Heigl continuing her journey as Izzie Stevens

Ah, I was wondering when the news would finally leak the can. Katherine Heigl is apparently due for another season on “Grey’s Anatomy.” Her best pal T. R. Knight, on the other hand, has been released from his contract after five years on the show.

Overall, this is good news all around, save for the George O’Malley fans. If the mountain of news over the last year serves true, both actors are getting what they want for the coming season. After months of clenching our fists over Izzie’s fate, fans can at least rest easy that her flat lining during the season 5 finale does not signal the end for Isobel.

Meanwhile, newcomer Jessica Capshaw (portraying Dr. Arizona Robbins) has been promoted to series regular, though this is hardly unexpected. It seems the sixth season should serve most fans well, but it does mean farewell for Dr. O’Malley. Does this mean he’s dead or leaving the hospital? Only time will tell.
