i heard about this months ago

nothing new to me

if you watch the campain and listen carefully its says something about armour on ghost

Why can't you just accept the fact that he's dead and Craig Fairbrass is returning to voice Wallcroft.Which is true you can check IMDB for proof,it lists the voices and the character their playing.

JerryTheWarlock wrote Infinity ward quoted ghost isnt exactly dead. What I think is that he is dead and will not appear in the campaign.

However, I think what they mean is that he will be some kind of playable character in survival mode or spec ops like the zombies crew maybe him, soap, ghost, and shephard or something.

What do you guys think?

In the one mission, Ghost asked Shephard: "Why do we have to wear these fire proof vests?" and in the mission where Soap (I think) and Ghost got burned only Soap was poured on by gasoline, not Ghost. Also in that mission, Ghost was shot in the shoulder, that wouldn't of killed him, only knocked him out. So, Ghost is still alive and he will reappear in MW3.

What I'm thinking is it'll be like a flashback level of the campaign like they did in COD4's mission "All Ghillied Up"
