The blur removal tool is NOT in the CS6 beta. I kinda don't think it will be in this release. It was shown as something that was being developed for a "future release" but not necessarily in the "next" release.
I have been playing with the beta for the last two days. There are some cool features where you can ADD blur to your photos to give it the look of a more shallow depth of field, etc. You can pinpoint the areas that you want to be sharp, control the amount of blur in other areas and even add some bokeh effects. It's pretty cool, especially for peeps like me that don't have an SLR camera and can't achieve those effects when actually shooting the photos.
Oh, and - what I read on Adobe's website yesterday said that you could get the free upgrade if you purchased after the next release had been announced. And, as far as I know, they have not announced an actual release date for CS6, so I don't think those of you that have already purchased would be eligible for the upgrade.
Me, I'm on CS3 and really want to get a suite next time I purchase since the last time I had a suite was with the original CS release and my InDesign isn't compatible with my OS anymore. I told DH that when the CS6 suites come out, I'm getting it. Luckily, we can get the academic version which saves us a TON!
