GraphQL+- will still be a thing, since GraphQL doesn't provide all of the things we need to manage a database.
That said, we're working on a pure GraphQL support, which will help with any kind of integration with other GraphQL projects. This is really exciting and will hopefully help many that do not want to spend their time learning Cypher or Gremlin and already know GraphQL.
Another project we're working on is offering Dgraph as a service. We're currently doing this with some of our customers and so we have the expertise and trust on our product necessary to run this service at scale. The ETA for this is not as clear but I do expect to have a private alpha by the end of the year.
