It's one of those point of view things. If you're only reading the SW books, then events are rare - this has been the first big one for them. Therefore, if you enjoyed it, why not have another next year? If you read Marvel more widely, it's event overkill. With a great many creative runs ending with a big, flashy expensive to buy event, as is the case with Zdarsky's Daredevil run. Previous recent cases are Aaron's Thor and Cates' Venom. From a wider Marvel reading perspective a title that tells its story on its own has become rare. With the frequency of events giving rise to a sense of fatigue, as people know the dance steps very, very well.
