Windows 10 will be free for Windows 7 and 8 users, which would be the majority of windows users.

I don't want to denigrate this conversation any further than it has been already. But it's not possible for all companies to be monopolistic. It's a little like saying "We are all the best." Also it's not surprising that iRay doesn't play well with AMD cards, as it's developed by Nvidia to showcase and make use of Nvidia developed tech.... I wouldn't expect to see any partnership between SM and Chaos Group in the near future either, so I wouldn't hold your breath about seeing any in house GPU support in PP2015. The DS bashing comment was not directed at yourself but at earlier contributors to this thread. 

"As we are said,what we are want to add,I want better GPU scaling,instancing etc.,do we are tried say anything about the DS where is bad.we are said,IRAY is not good for us who owning AMD card,bloody hell,please read!" <-- This is "Bloody" pure gold!
