Lightroom 4 Beta Soon?

Lightroom 4 Beta to be released soon?

I was recently on a Photo workshop with a well known Lightroom 4 beta tester who also writes books on a particular aspect of Lightroom. He let slip his new revised book on Lightroom 4 is set to be delivered to his publisher in February 2012 and that we should seeing a Beta version of Lightroom 4 released very soon. He also intimated that there may be a few surprises in store especially with the Lightroom user interface, but he was pretty tight-lipped about exactly what those surprises would be.
