If he didn't work on the book, it doesn't really matter what he has to say about the canonicity of the book.
O.k, to the first part, but the creator's of those titles said they were.
I work for Marvel. If I say that Avengers is non-canon, does that hold water?
If you were on a public panel representing Marvel Comics in a public forum, which is reported on by outside news sources such as CBR, Newsarama, Wizard, ect... I would take that to mean thats Marvel's stance on the mater, unless they later retracted your claim, at least as far as Marvel is concerned.
I just found it amusing that a fan hit them with it, again. Only to have an issue come out the same week from the same series with another huge continuity issue. Also some preview art from X-Men Prelude, shows them once again in their "First Class" outfits.
Maybe since you work for Marvel, you could suggest a "continuity" editorial team, that would eliminate any need for debate about the issue. Since they claim one thing in solicits, interviews, handbook entries, public announcments, and then give us the product which is clearly flawed and could fixed by taking out one line of dialog or name.
I'm all for this being a seperate universe that could be later evaluated like the Ultimate line, Marvel Adventures, 2099, Max, Earth X, or any others.It being "canon" unto itself, does not bother me, its that Marvel just keep announcing otherwise and it keeps it in "limbo" here.
