Eugeni - we are currently working through the release process and need to ensure all the tasks/signoffs are completed before we are officially approved. That said, we had targeted to have the v12 release for sometime in the last quarter of this year - and continue to work towards that. Keep checking the SCN or ADS forum for any further news. As for your question related to buying v11 and then being eligible for v12, you would have to be on an annual maintenance plan to get upgrades to newer versions.
