Some of the new books appear to be replacing current books, such as All-New's cast being close to Gold's and Extraordinary's similar to Blue's. And since Blue and Gold are biweekly I doubt they'll keep all the current titles.
The one I think might be kept is Uncanny. Most of it's cast has yet to be seen in ResurrXion-related stuff, and it would be weird for Marvel not to publish an Uncanny X-Men book (not that they've never done that).
