I had hoped it would just be some lame ME multiplayer spin-off rather than ME3. After all, we all know ME3 is coming, so all the teasing seems an odd play. However, a recent announcement by EA that single player is dead and they won't be releasing SP only games any more
does seem to add ammunition to the idea of it being ME3 with MP included. If that turns out to be the case then Bioware's journey to the Dark Side will be complete, and they will be truly dead.
