The more I see of this, the stranger its getting. I could understand the "Ghost" in the title being...well...Ghost from MW2, either in prequel or sequel form. But if its gonna be Ghosts plural, either Ghost and Roach are alive and its a sequel (an alternative view of the events of MW3 maybe?) or we've got another franchise that refers to Ops teams as Ghosts
. In the event of the latter, I think Ubisoft might get a bit sore if there's more similarity than just the name.
I'm hoping for a Ghost n Roach reappearance, but as we're (as usual) left playing the speculation game for a while longer, it could be any, all or none of the above.
