Next release of PowerDesigner?

Hi gurus,

Do you know where I can find documentation on timing for next release of PowerDesigner and end of maintenance for PowerDesigner 16.5 sp03?

So far, all I've been able to find is a SAP document from 2013 that indicates end of mainstream maintenance for PowerDesigner 16.5 in February 2015.   Is that still the current plan? What release succeeds 16.5 and when will it be available?

Thanks in advance your help!

Ann
