HTC made a comment on a a Facebook page that points towards an update heading to global variants of the HTC One X, HTC One X+, HTC One S and the Butterfly. The wording of the reply is very careful to not state anything specific or any specific region. With wording like ‘some’ , ‘next few months’ and variants. We all know that usually means that international versions will probably see it and U.S. version won’t see one for quite a while after that, if the carriers even decide to make the update.
