I've been following the news about project XBR and I attended the latest Autodesk webinar on it. And believe me or not, Max 2012 is more than just a new yearly version and it's just a step closer to final project. The project started earlier by max 2010 and improved a lot in 2011 and there're many improvements in 2012 too.
