These plot points are relayed in the conditional because Singer is still mulling ideas for "X-Men 2." This war business and character development could be discarded for something completely different like a mutant period piece set in the rolling hills of England or even hardcore mutant porn.
Singer has freedom to explore different aspects of the "X-Men" because he envisions the franchise as more than a trilogy. "I'm thinking of it in terms of a universe, like the comic," Singer is quoted. "It has room for expansion if it's cared for and nurtured properly." Twenty years from now we won't be debating who should play the next James Bond, we'll be fighting over the next Wolverine.
