Is the montrer signed up for a 6th season and if so whose definatly coming back?

the actors are signed on for 7 seasons. and i think they are for sure coming back for all 7, because they are still one of the haut, retour au début shows of tv.
of course, actors may come and go, as we have seen with all those cardio seurgons, but they are staying.

I've read all of the cast has signed except Katherine Heigl (Izzie).

izzie is leaving after this season she wants 2 start jouer la comédie in plus movie

Yeah and there's also a 7th season, But we'll never know who'll be the actors they always die and go but ofcourse there'll be the main characters Meredith, Derek, Christina, Mark, Karev, Miranda, Richard and maybe Lexie not sure but we still dunno if izy's staying and George's gone

Yeah, the actors are signed for 7 seasons. I have seen talks about Lexie getting the lead role in season 8, but I think think it's just our wishes if some of the lead actors quit. :D

I think there will be a sixth season with Mer, Derek, Mark, Alex, Lexie, Cristina, Owen, Bailey and The Chief. I'm not sure about Katherine because of Izzie's cancer and T.R.
