I'm pretty sure the solo movie is planned to be a prequel about Weapon X, so they could still kill Wolverine off. Maybe they'll kill Storm at the beginning of the movie so they won't need to cater to Halle Berry anymore.
As far as Moore movies go, From Hell is really the only good movie based on a Moore book, and ironically the only reason it was good was because it didn't stick to the material. The book had way too many layers and way too much exposition to make a faithful adaption and in that case the filmmakers knew what to get rid of and what to keep to make a concise story. Sure, it didn't have much of the brilliance of the book, but it could be appreciated on its own merits as a pretty good movie (unlike, oh say, LXG). I know I take potshots at the Wachowskis a lot on here, but come on. Based on their last few movies, I'd say editing long exposition into a tight and cohesive story is not really one of their strong points.
