According to The Telegraph The Beatles will release a new album to mark opening of a Las Vegas extravaganza with the acrobats of the Cirque du Soleil interpreting the songs.
It's a little unclear what they are doing, though the article notes: "The producers will have access to unreleased archival material, including 200 hours of recorded conversations between the Beatles in the recording studio."
And, another new Beatles set; The Capitol Years, is released tomorrow. I gather it has the mono and stereo versions of the early Beatles albums in the "U.S." format; remember that Capitol released versions of The Beatles albums that were very different from the U.K. releases.
Having grown up with the U.K. albums, I guess I'm not as enthused about the idea of getting the U.S. versions (though I know how disconcerting it can be to be used to a particular track order and have things change on you.)
As to the stereo/mono debate; George Martin (and Paul, George and Ringo) felt that mono was the 'right' way to hear the early albums, and did that for the original CD release. Don't forget that when the albums were first produced, they were only mixed in mono, the stereo mixes weren't even made by them.
But hey, if people will buy it, why not sell it to them?
