So far, only a small group of wikis has actually migrated to Discussions - ones that were started several years ago and had zero forum content. Most communities that have Discussions also still have their forums that they can use while Discussions is still lacking features that are important to them.

We're currently working on the first of several larger feature additions, which is why you haven't seen any bigger updates to Discussions in a while. Of course that can make it appear to users as if nothing much is happening with Discussions - but I can promise that we are working on it, and you should see another update soon.
