the fallen are going to return but most of the focus will be on the taken. there is new hive content confirmed cabal content confirmed and vex content confirmed I'd be shocked if the fallen DIDN'T have anything at all. especially after all that development in house of wolves.

Yes, but in a taken version with different abilities. If you're talking about the regular fallen, then they're probably not going to play a big role. Unless they side with us (like an arbiter type group) then that would be f*cking awesome!
