re: New FX series Legion (of X-Men fame) is deliciously insane

Looks amazing, can't wait for this.

This is from one of the posters, pretty good description if you are not familiar.

"Is this like based off Legion from the Marvel Comics?? The mutant son of Professor X who inadvertently brought the Age of Apocalypse in and suffers from multiple-personality disorder to an extreme that if the emotion or mutant power he spawns (he can't basically make any sort of mutation to himself, granting him whatever power he wants but every time he does he makes a new personality) is particularly strong or evil or w.e it separates itself from David and he has to hunt it down to reabsorb it, so does that mean X-men/factor/force/etc cameos????"
