Not sure if you guys have been playing with this, but if not, I think you should, especially for the the product render folks. The Iris Blur is a hell of a tool to create better ground plane reflection blurring effects of your product in Photoshop. It's not perfect but is quicker, easier and gives a MUCH better result than dealing with gaussian blur or lens blur filters. Not to mention, they finally give you a dark gray working environment for your windows and palettes! Below is the download link for the curious (this sounds like a shill but it's not, I've just been extremely impressed with the Iris Blur):

I've tried for some days. It's looks very nice. Especially I like video editing feature. 3D feature is good too.
But I have no plan to upgrade my CS5 to CS6.
So I'll uninstall it before it shake me up.

While I don't see truly earth shattering new features there were several nice workflow-enhancements and cool new Filter which make all expensive Dof-Plugins superfluos.
Also due do the Mercury-Engine Performance got a remarkable boost. With my five years old Laptop CS5 startup could take 15 seconds or so - CS5 needs 5 seconds max.
