Often when marvel releases / threads are created, the official artwork is usually still pending. This was kind of different due to the fact that official artwork was released immediately. The confusion was that if the art would change as in many other titles but was quickly confirmed that this is the official artwork. Like
@apsmith21 I think the releases worldwide are likely to see the same artwork even though there might be some variation in finishing. I wouldn't be too surprised that when Zavvi finally update to the final artwork, it is the same.
