Will all the titles that came out before Secret Wars be not part of the same continuity in the New Marvel Universe? Will all the characters not remember the events like Civil War, Secret Invasion, AvX, House of M, so on and so forth?

I've read the All-New All Different Avengers and that doesn't seem to be the case because Kamala mentions that the Avengers were started by the Wasp, and Miles mentions something about the Avengers not having Stark money and such.

But a part of me still feels uneasy that our beloved characters will not remember the events before secret wars, especially because I also heard a rumor that the Silver Surfer reshapes the Marvel Universe after Secret Wars or something like that....

What do you think?
