Thank the X-Gods! No Gambit in X3!

"Today, Ralph Winter (one of the film's producers) confirmed to The Xverse that there is no appearance by Gambit in X-Men 3 -- but that it might be included in "the next one". This indicates that despite any possible plans to end the series with a trilogy, people involved with production are open to future X-sequels."

Thank you! Thank you! Thank you! Thank you! Thank you!
