Loads of information over at Photoshop News, along with tutorials and a link to Martin Evenings CS3 book. There is a free download of the first chapter. This does apply to Lightroom in a big way because Camera RAW 4.0 Beta is included and contains features found in Lightrooms Develop Module, including Fill Light, Recovery and Vibrance. Hopefully this will bring XMP compatibility between the 2 programs.
Update Martin Evening has confirmed that his beta (later than 4.1) is compatible with ACR4 and CS3. Tom Hogarty has also indicated that there in still no proper compatibility with B4.1 though.
