I'm gonna go on the record and say that Fo4 is gonna have all the same character customization options as Fo3 did, simply because Bethsoft, for all their foibles, is still not Pants-On-Head Retarded and isn't going to go backwards in terms of accessibility, especially not after Ubisoft caught so much flack for not having playable female characters in Unity (and after having a playable female character in Syndicate shut so many of them up.)
