How and when will Explorer functionality migrate to Lumira?

Two years ago, SAP announced that Explorer functionality/use cases would be folded into Lumira as part of the convergence of the SAP BusinessObjects BI product portfolio. While many aspects of Explorer functionality exist today in Lumira, some of the core search and exploration features are still missing and Explorer is largely unchanged in BI 4.2 from previous editions. What is the current state of convergence?

1. Will Lumira become a viable replacement for Explorer sometime in 2017?
2. Will existing Explorer information spaces and exploration views either work as-is or migrate into Lumira?
3. Will there be any kind of design council so customers and partners that rely on Explorer today can influence the final solution?

Thanks!
