I know that many of you have asked about a roadmap for PowerDesigner. We did publish the updated roadmap on SAP Service Marketplace in October 2014. The most current roadmap is available to customers through this link http://service.sap.com/saproadmaps and PowerDesigner is listed under the Database & Technology category.
Additionally, we will have a webinar covering the current PowerDesigner roadmap on January 13, 2015 from 9-10am PST. Please register using the following link. http://service.sap.com/~sapidb/012002523100019949392014E
Keep on modeling!
