The "rumor" I just heard from the latest speaker is that Revit 2012 will include the Solar Analysis tool that had previously been an Autodesk Lab's plug-in, and then was rolled into Project Vasari late last year with its release.
Autodesk is also pushing sustainable design and that they have products that match all levels of design. I think the one caveat to that is that the wonderful narrative they just spun relied on several (more then three) tech previews on Autodesk Labs..... I don't know about you, but most companies don't like to use products that have "expiration dates" with no guarantee of renewal on projects that may continue longer then the life of the "product", or at the very least we need to access the data later.
Another important note, Autodesk is re-packaging their software into Suites (similar to Office or Adobe), all well and good, and it will be great for small and medium business. What I think is really, really cool, is that Sketchbook Pro is included in all the suites. Why is this important you ask? Well prior to the 2012 release Sketchbook was always a stand-alone license and if you were in a large network environment that was problematic at best. Now with the suites, if you buy network license versions Sketchbook is part of that network license pool, which is great! Now you can make it available to anyone to play with, use or do whatever they want!
