I’m presuming you came across this article on the For Your Marriage website:
Marriage Rite, Second Edition, What’s New?
I have no secret knowledge, but from the article, he says that the U.S. bishops voted and approved the translation at their November 2013 meeting and that the next step was for Rome to approve it “hopefully in 2014.” Given that it is now 2015 and your Google searches cam up empty and I see no mention of the Vatican recognitio having been obtained either on the Vatican website or the USCCB website, I would presume that the author’s “hope” is as of yet unfulfilled.
In other words, it hasn’t happened yet. The reason you can’t find any information is probably because there is no new information. Eventually, it will receive the approval (or be sent back to the bishops for more changes). Then I’m sure there will be more articles written and press releases made. It’s not altogether unusual for these things to take longer than anticipated.
