MW3 leaked official video by activision

i found this video online , i dont want to give the source away but i re uploaded the video to my youtube and it looks like its a teaser for mw3 . it video shows the mission where ghost dies and there are some rumors floating around that mw3 will feature u playing as ghost . take my word as a grain of salt and judge the video for yourself . i think the video is legit and it looks ballsy
