With the new feature of 'Timeline', is it possible to build reports off of this object?

+1 use case.  Our User Research team has their own "Activity Type" in Timeline to document user research sessions in Timeline.  We would like to be able to create a report and surface that report in the R360 to summarize all User Research sessions that have occurred so the CSM does not have to comb through timeline.  

Reports on Timeline data coming soon!  However, Melissa, please note that you can always filter down the Timeline to only the Activities of the type you mentioned so you can see just those rather than having to scroll through lots of other stuff. 

Any visibility on when will the reports on timeline be coming? 

Reports on Timeline data are in the product now. (Apologies that we did not update this thread.) Use the Activity Timeline source object.  Note that currently this object does not include the Notes or Attendees sections.  Including the Notes section will come up in next release. 

We did a presentation at Pulse on Timeline and covered some examples of the types of reports you could generate. 

Here are the slides from that presentation (look about 2/3 of the way through the deck for the reporting slides): https://www.gainsight.com/pulse/2017/recap/assets/pdfs/Highly%2520Evolved%2520Collaboration%2520Made%2520Eas...
