The online sounded like it could be intriguing. I don't know if it's a certain mode, or how the whole thing plays out...but, basically you have to work together with everyone to pull off the job. Then once the job is to a certain point you can decide to double cross your partners and try to take the loot for yourself. Then when going to the next job, the person who betrayed the team will be noted by a different color or something.
It sounds like it could be a lot a fun if done right...at least they are trying something somewhat new.
