>>10801620give it 4 months and we'll probably know. Any news about new or returning themes gets leaked very early.
Bionicle or not, the trajectory is clearly pointing towards mechs and robots and lego going full hog on it.
Bionicle, Exo-Force, Transformers, new theme? If you can't see that something is on the horizon you are blind. It's very clear the mech sets sell incredibly well.
