We have an active Singleplayer campaign under design, but for this first release we are concentrating on a solid MP experience with the unique core gameplay elements in place. A second release will bring with it the SP campaign as well as a Co-op experience.
Well, then I will be waiting for the 2nd release as you couldn't pay ME to be interested in the MP part of any game.
All I play is SP and co-op and have for the last 10 years, whether in a tactical sim, flight sim, FPS, RTS, you name it. I'm not about to change that anytime soon (I feel the same today as I have for the last 10 yrs, so why would tomorrow be different?) but when a good SP campaign with co-op is out I'll go for it.
I just hope it's "true" co-op like they've stated. By that I mean the SP campaign and other humans can take the roles of those on your team, not like Splinter Cell or Rage or ME3 or some of these others were co-op exists separate from the campaign, whether or not it has any bearing on it/is a part of the larger story. In those cases you tend to get at most half as many co-op missions as SP, if not fewer, and you burn through them way too fast.
