Answer Re: sccm r2 out?
Yes, the R2 release of Configuration Manager 2007 did reach RTM the other day. The evaluation version is available for download. The non-evaluation product is not a free download unless you are a software assurance customer. If so, then you will be able to download the non-evaluation version. If not, you'll have to purchase the R2 software.
As to when the non-eval software will be downloadable, I don't know for sure, we don't control that part of the distribution process.
