I don't know if Marvel is ever going to give the ANAD Marvel Earth an official numerical designation, and it really doesn't matter.

Just like it doesn't matter if the posters on the board who were swearing up and down until a few months ago that the new Marvel Universe was just going to be a revamped Battleworld, and we'd never get a recognizable Marvel Earth with the usual continents and nations, or a recognizable larger solar system, universe, etc. around it, ever post their retractions now that ANAD has started to come out and made it clear they were dead wrong. Though it would be nice.
