I find it a very very bad idea. Since there can only be one Shepard the second player will just be a henchman that gets nothing as seen in all the single player games that have done this. Also they failed even more as a single player game also.
I still hope this is not true and even if it's true there is plenty of time to make them change their mind over an so obvious bad idea. Thing is making Mass Effect 3 the best game of the serie is pretty easy just combine the action/fighting/moving part from ME2 with the RPG elements(minus combat) from ME1. I wouldn't even mind the vehicle section beeing brought back since it was good enough in ME2 as long as it's flying/hovering vehicles.
