Couchbase Server is different from Apache CouchDB, etc (different APIs, different use cases, etc). But our mobile database, Couchbase Lite, is sync compatible with the Apache CouchDB ecosystem, and it has a vibrant developer community: https://groups.google.com/forum/#!forum/mobile-couchbase

I'm glad Cloudant are sticking with the standard CouchDB sync protocol. Their mobile clients are based on open source code started at Couchbase, so they will be able to connect to all the existing backends, including Couchbase Sync Gateway.

This plus PouchDB and the other new entrants, I'd say is one more reason for developers to consider the Couch ecosystem for sync.
