User blog comment:Commdor/ME3 to Have "Killer New Feature"/@comment-4069499-20111001215927/@comment-3268946-20111002033035

From what I have heard, they are keeping the interrupt system from ME2, plus the Kinect interactivity, I doubt it involves dialogue. I am more inclined to believe that it would be a Horde mode clone, but only because I adamantly refuse to believe that full-fledged multiplayer would be included.
