I'm 52% complete I believe. I just finished a mission where I had to retrieve an armored truck. Afterward I have ZERO missions on my map. Of course my objective is "Start your next mission". Kind of hard to do that game!
The mission prior to that it seemed like I had to save and exit my apartment before a mission would show up. I tried that again this time and nothing.
Games I am currently playing: Dead Space Extraction (PS3), Dead Space: Ignition (PS3), Dead Space 2 (PS3), LBP2 (PS3), GT5 (PS3), Madden 11 (PS3 & 360)
