In a way, I think WB being more restrictive for the Horror front may actually benefit Universal Hollywood; as it may be the force that gets them to move towards more of an "original" event, to stand out against WB.
Now, I'm not talking all originals, but I think we need to look to how Orlando..somewhat mixes the two. I think it's huge of the potential with Netflix, and there will always be smaller studios.
That's just my thing, but it matters more to what lies for the future of the event going forward.
