Here the text of the mail. Jeff Christiansen wrote: Despite similarities, Reality-92131 is the X-Men cartoon reality, which is not the same as the Adventures of the X-Men series reality.

Further, "Earth-0" is specifically in quotes as it is not a true designation. It is a reality designation for a reality from the previous multiverse.

Regardless of the designation of "Earth-0," it is not the predecessor of Earth-616. It is just the reality that brought about the end of the previous multiverse (via the M'Kraan destruction). After that, a new multiverse arose, of which Earth-616 is only one reality. The information is covered in the OHotMU entries on the M'Kraan Crystal, Galactus, D'Spayre, and the Dweller-in-Darkness, at least. Possibly also the Phoenix Force +/- the Living Tribunal. The M'Kraan and Dweller have Appendix entries, which should cite all sources of information. <

To sum up (because my message was written very quickly):
 * Adventures of Spider-Man and Adventures of X-Men are in the same universe (there is a titles cross-over), which is also the last universe universe of the previous Multiverse, where Galan lived. For all the other series, I don't know (never read them, haven't got a clear answer from anywhere).
 * Those other series are either 92131 or a TRN, or "Earth-0", don't know.
 * "Earth-0" isn't a real reality designation, but "a reality designation for a reality from the previous multiverse".
 * I don't defend "Earth-0" as a page title because (to be clear), it isn't a real name (that "Earth-0" would go into notes or other way to highlight a fan-based name like for other page). A TRN to replace "Earth-0" is an interesting idea (to cut down any belief that Earth-0 is an official thing), and also to allow us to create the disambiguation for "Earth-0", Earth-000, etc.
 * There is nothing clear about if "Earth-0" is Earth-616 or not. Using the latest example to say it is is far from a good idea, because that would be comparing two very different things. I stand by the the handbooks given the lack of clear statement in the comics (who talk about "restauration", "recreation", "new universe", etc.)
 * I hoped that Ultimates and New Avengers would bring up more stuff, but nothing as far. Mor-I-dun (5th Cosmos) was especially shut down way too quick.
 * In All-Different, All-New Marvel Universe, it is even stated that the new mainstream universe is "Prime Earth" and not Earth-616 (even if Prime Earth is the merger of Earth-616 and other stuff).
 * Like Nausiated said: Ressemblances and continuity issues aren't really helpful because some writers doesn't care. On the other hand, when an handbook use specific events in their issues (and the writer confirms it by mail), I go by their interpretation in lack of something else.

For the rest, as far as I've seen, given the confusion of Al Ewing for Uni/Multi/Omniverses, I think it would be way better to wait on what's clearly defined until other clear statements.
