Since CoV and CoH all share the same codebase and resources, why wouldn’t you be able to get CoV costume parts in CoH?
Answer: You probably will.
OK – here’s the most likely outcome…
If you own both games, you get all options – the new CoV sets will be accessible for your heroes.
Granted, most heroes don’t go around with barbed wire headbands and exposed brains and the like — but, then, that should be a player decision. If there’s no technical reason to prevent it, it shouldn’t be restricted.
If nothing else, it will be cool seeing “cat girls” with the CoV Cat Face feature. Not sure about “War Wolf” heroes, but, well, heck, why not?
And, of course, this eases (or does it trivialize?) the Villain Goes Good mechanics.
Now — when will this happen? Again, no reason (I can think of) why it wouldn’t be doable from Day 1, but believe it when you actually see it.
