Indeed. New Captain America is coming. Thor will be a brand new female character. (Even though there is already an existing Thor Girl).
And with the popularity of both of these characters (Cap and Thor) with their movies - and they're making these bold moves... if one thinks they won't tamper with the X-Men in a major way (or all "mutants" - well that's just silly!) Like I have been saying - they won't cancel the X-Men - EVER - but I have a feeling they're going to do something that allows Disney not to fook around with FOX and movie rights.
They had Dark Horse stop their run of STAR WARS (here very soon) - and what is Marvel doing?

Releasing their old Star Wars comics again.
Disney wants to capitalize in every regard. And if it means changing X-Men to something else - I see it happening.
