Do/will Marvel characters remember the old DC universe (pre new 52)?

Or were all of those crossovers non-canon?

JLA/Avengers was New Earth and Earth-616, yes. And Marvel would remember it as happening because the New 52 is a new universe, Prime Earth, not New Earth.

All of the other crossovers happened in different universes, though.
