Sounds more like MP integrated into other SP-only areas.Like we noted last week, the process was a bit different this time around. The multiplayer spaces were still constructed separately by a team of trained multiplayer experts, but as each arena came online they were subsequently passed over to the campaign team and injected into the game in progress as small portions of much larger campaign missions (which should explain the information coming out of X10 last week).
