Since the original Crisis was done to consolidate the different universes, and the others were to iron out the problems that popped up since then it makes sense. So, should fans be happy or not? I don't know. They were (for the most part) good stories, especially the original. On the other hand, with the new timeline I guess they aren't really needed. Thanks to Bleeding Cool for the heads up.
