"This from an email Dr. Craig Evans, the Payzant Distinguished Professor of New Testament at Acadia University and Divinity College, sent to me [Dr. Daniel Wallace] earlier today. He said that Helmut Koester (Harvard University), Bentley Layton (Yale University), Stephen Emmel (University of Münster), and Gesine Robinson (Claremont Graduate School)–all first-rate scholars in Coptic studies–have weighed in and have found the fragment wanting. No doubt Francis Watson’s comprehensive work showing the fragment’s dependence on the Gospel of Thomas was a contributing factor for this judgment, as well as the rather odd look of the Coptic that already raised several questions as to its authenticity." -Dr. Daniel Wallace
Quoted from Dr. Wallace's Blog at: Jesus' Wife Fragment Judged A Fake

Dr. Wallace has published another brief blog post that seems to indicate Harvard has changed its mind. There seem to be some conflicting reports: "After I posted the news which I received from Dr. Craig Evans that HTR was not going to publish the fragment because it had been judged to be a fake, I then got news that HTR was going to publish it. Here’s the link that gives the data": Religion News.com
