Fallout: New Vegas' "Mr. Vegas" to be Voiced by Wayne Newton

During this week's E3, DasReviews managed to convince an Obsidianite to reveal that Wayne Newton will be voicing "Mr. Vegas" in Fallout: New Vegas. Should be interesting:
We had always suspected it but now its official: Wayne Newton aka Mr Vegas will now be called Mr. New Vegas. Yes, that's right! Wayne Newton is an official voice actor in Fallout New Vegas and he plays Mr. New Vegas. Das Reviews got an exclusive tip from someone at Obsidian during our E3 visit.

Can we possibly see an in game rendition of Danke Schoen? This would definitely complete our post-apocalyptic Vegas trip. In the event of a nuclear holocaust does the (What happens in Vegas, stays in Vegas) rule still apply?
