Mass Effect 3 - Multiplayer Indications?

CinemaBlend has noticed a job advert that would seem to indicate multiplayer will be a feature of Mass Effect 3:

Maybe "suggests" is too weak a verb - the BioWare Montreal opening (picture below) is for a "Multiplayer Programmer (Mass Effect Franchise)." Not much room for interpretation, there. The ideal candidate will have to come up with "solutions to deal with network latency, de-synchronization of data between networked machines/players, packet compression, cheating, and interrupted connections." They'll also have to "work with databases that allow for chat rooms, client/server games, player matching, player stats, etc.".
