Sinofsky may be gone but I suspect it will take some time to clear his influence. And as long as that influence remains, MS will be keeping things under wrap for Windows v.Next as long as possible, unfortunately.
Unfortunately I believe you are correct. Culture takes a long time to change. I for one am not anticipating any major shift in Windows Blue. Maybe an improved store experience, a few nits polished off, but not any major shift like share contact support for desktop apps.
