A few interesting tidbits out of the keynote this morning by Nicolas Mangon.
Point cloud support is coming (someday) to Revit. Nothing specific, in terms of time, but I would say '12 or '13. This information supports my suspicions as in '11 you'll note a bunch of .dll's for "AmberCore" which turns up some interesting Google results.
Another interesting note, it sounds like for MEP '12 we can expect to see a focus on Plumbing/pipe development/improvements after this years focus on M and E improvements.
