I'm also very curious about CouchDB 2.0 and whether CouchDB will be able to make a comeback. When I talked to Adam Kocoloski about a year ago, I got the impression that it takes a very good technical approach (consistent hashing, causal hash histories, MongoDB queries, etc.). However, the implementation is now mainly driven by Cloudant and CouchDB kept alive by them. I hope they manage to rekindle the old fascination they once had. In any case I will be happy to update the article and include it.
