Well, they spoke of story developement in the last warriors den. If they did put in new single player missions ... woah. i mean: they would give us something cool and unexpected. People would love them for it. Try out the new heros, experience new enviroments and revelations.
But seriously? Would be too good to be true. Might even yield positive press. Though it seems the press hates Ubi. Like them telling you new heros are ultra-overprized because they are like: 1 new hero is like 30 times the original ones! and that might sound much on paper, but it isn't in reality.
So in the end - i highly doubt it. Would love it, but ... who cares?
