Microsoft announced pricing and licensing models for their SQL 2012 release sheduled for Early to Mid 2012. Client access licenses up by 25% and a move away from per cpu pricing to per core licensing for Cal-less enterprise product.
Only benefit seems to be up to a 400% increase in performance for transaction based loads, but something tells me that the majority of users will not see this result without some serious optimisations to their structure and code.
