IBM announced on Analytics Zone yesterday the first (smallish) step towards integrating Cognos BI and Watson Analytics, which has me super excited. To start with you will be able to browse Public Folders & My Folders and upload data from the list objects contained in RS/CWA reports, much like you can currently in Workspace.
IBM announced a host of other new features for WA, I'm guessing to help build hype for Vision 2015. If you're going to Vision let us know what they show. And if you're interested you can check out my blog (linked below) for more info about the new features.
Cheers!
