If this movie is just a straight-up sequel to First Class, without the cast of original trilogy, this movie wouldn't even have this kind of buzz right now.
In 2011 XMFC was a total unknown that had to come off of back to back poor movies in this series. That isn't the case anymore. FC was a success and its lead actors are now amongst the hottest of the hot in Hollywood. A straight up FC sequel would have generated enough buzz on its own and it would have been a very highly anticipated film for 2014. Obviously when you combine casts there's going to be greater buzz.
