Roadmap Systemplatform and InTouch

Hi all,
i have been contacted by one of my Systemintegrators in Germany who is battling against Siemens (Win CC and Win CC OA). Our friends from Siemens promised the enduser a long terme availability for the mentioned products as well as a roadmap for those. Do we have a longterm roadmap for SP and InTouch as well in a documented manner with steps and improvements? The SI needs this to secure our position at the enduser..... Thx and BR Michael
