No word has really been said about GoW3 yet. They will not release a spoiler like that until the game is released.
As for my theory, the Gears Of War Franchise has expanded larger than just the trilogy. The book series will go on after the trilogy, as well as spin-off games. I don't think Marcus will die in the next game but I am expecting a main character to be killed off. It just feels time *COUGH* Baird *COUGH* ;)
Marcus fenix
griffin and marcus
No, he doesnt die, but Dominic Santiago does. He is shot in the back by Queen Myrrah. No other character in the game, that you like that is, dies.
It's Marcus dad
He died cause of the loucoust
Yes i do because Marcus dies in gears of war 3 and i think Barid does as well.

He's in prison for dereliction of duty. http://gearsofwar.wikia.com/wiki/Marcus
