It's a shame, I used to think very highly of both actors, but this has just about ended it for me. Seriously? You don't get enough screen time? With the exception of this season, the two of them have been involved in almost EVERY major storyline the show has ever had. The two main characters were pushed aside for their relationships early on, and don't even get me started on Gizzie-Fest 08. Now the Main characters are getting some well deserved screen time and they are complaining? Sure, TRK hasn't had as many scenes this year as he usually does, but I think that's partly because from all accounts he's been whining to anyone with an ear. Plus, there were times when we didn't see some of the other main characters any if at all in past seasons and they didn't go huffing around about it. And Katherine? Show business has gotten to that woman's head. She can't be grateful for the show that made her a *name* at all, she whines when she's on screen or off, and she blames the writers for her attitude.
Again I say... GROW UP.
It's TV. It happens. People don't always get set numbers of scenes or storylines a year, and you should be thankful that you are getting paid for only doing a few scenes. PLUS, you should be thankful for all of the other HUGE storylines you've been given in the past, and understand that with a cast of two million you aren't always going to be the main spotlight.
While I'll be sad to see both characters go, the actors themselves not so much. I'm so very disappointed, in TRK especially. Of every actor on that show I thought that he would be the most down to earth and humble one - guess I was mistaken.

Don't let your career hit your in the arse on your way out. =P
