There's another possibility. Some other entity (maybe a new Queen of Hearts, for example) is in a war with Ana, and one of the acts of the new enemy was to somehow banish Will from Wonderland. That would not necessarily retcon the ending of OUaTiW, but would easily explain why Will is not still with Ana at the present time.

And I don't see Will asking to borrow any of Maleficent's mirrors any time soon. ;)
