We now have a new TechNet library site for SBS 2011:
Note that the Support and Troubleshooting link has not gone live yet.
SBS 2011 Standard version along with all SBS related products will have Windows Small Business Server 2011 Premium Add-On SKU (near the bottom) for the additional Windows Server 2008 R2 Standard OS and SQL 2008 R2 Standard. Given that there was a separate SKU set for SBS 2008 Premium CALs, we can expect that the same will apply for this new Add-On SKU.
