It's about time Billy Coen returned. We haven't seen that guy in nearly 20 years, so a third Revelations game would be perfect for his comeback. Technically, it's about 20 years in the franchise's overall timeline by this point, as Zero took place in 1998. It's just so sad how he's another major character they just threw into the series for that one game, like they did with Sheva in RE5. Anyone who conquers an Umbrella official has to be considered as being hot stuff, right? Plus, Rebecca has came back, so I think he should someday as well.
