EXactly, I think we will have another (mini) wave of #1's in the February solicits to take us to the end of the Krakoa era.
Honestly I always thought New X-Men was just a continuation of Gerry Duggan's X-Men with a new team but I don't really think that's the case now. The Apocalypse theory sounds more believable but I wonder if there's some alternate reality stuff involving the actual Age of Apocalypse... we did have Colossus in his AoA costume in Mark Brooks' teaser after all.
Regarding Original X-Men spinning out a new book, I have to wonder if the timing works out since we're at the end of an era. Unless it's a limited series debuting in February and concluding in May/June. I still cling to my theory that the "original" who remains is Changeling/Morph :P
