Cannot confirm anything before it is official.
New releases usually come every six months.
15.2. having come out a while ago the next release could come again in the fall prior to CA world.
Roadmaps are presented inn user group meetings.
If you attend the end of sprint demos in the user validation group you get a little more likely idea of what could be coming in the next release.
Personally have not heard anything about other reporting tools, however, people have been using them before and then have build their own ways of connecting and security system and launching from ca PPM.
