Re: ***Official X4 Campaign*** [JOIN US!]
DOFP isn't really X4 especially with the cast of First Class being in this movie.
AND DOFP isn't the closest thing to a X-Men 4. The producers had a back-up plan for X4 incase First Class didn't end up as a success and that X4 leads to X5. There's always a possibility for a true X-Men 4 movie.
