The 2013 bags had unpainted, glow with guts Deathras. So if there's Deathras, they'll probably be different. I'd like to see more unpainted headless Houkai or maybe complete sets of the Moai toys in each bag. Even if colors varied, but full sets.
How about a new transforming Cyborg head or some random cyborg mech parts like arms or legs. edit: Cyborg already has a chest. duh.
Another walking killer would be nice! I really liked both killers that showed up in bags last year. Though seeing a sleeping killer in bags would entice me to pull the trigger for sure.
