Are you in the US? Because here, X-Men: The Last Stand
was only released as a 1 disc DVD. Only the Blu-Ray has all those extra features.
And also, reading all the articles that are talking about the X-Men: First Class
Blu Ray / DVD, there is nothing indicating that it's a 2 sided slip cover. Everything that I've read makes it pretty clear that it's an "either / or" situation.
