Breaking News: At the 10th International Congress of Coptic Studies (meets every four years), Karen King has revealed the possible existence of a new gospel, of which only a fragment (in Coptic) survives, that says, "...Jesus said to them, My wife..." Initial testing has suggested it is, indeed, ancient. See discussion here, which contains a further link to King's paper.
April DeConick has a short comment on it here. See more here and here, leading to other sites.
DeConick has a fuller translation of the fragment with discussion here.
