This close to the show and things are still happening.
Apple released the 10.0.4 update for FCPX yesterday and I believe Matrox, BMD and Aja have all now released updated drivers also, Please make sure to update both the software and the hardware drivers at the same time, word is that there are a number of fixes that resolve many of the hardware related issues.
Avid has really been hyping Avid Motion Graphics and it will be a big part of the Avid Booth this NAB
Autodesk has also been pounding the street about the "big" changes that are happening with Autodesk regarding Smoke at this NAB, while time will tell, we only have a few more days to wait.
And while NAB is always about the hardware and software tools, let it be known that some people are actually working torwards making life better in Vegas. Gizmodo is reporting that a zip line is being planned to connect some of the casino's. I am hoping for one from the Marriott to the middle of the LVCC South Hall http://gizmodo.com/las-vegas/
