The team is a bit burnt out from making all of those awesome pronunciation trainers, so we are taking a break for a little while. It's a possibility that more might be made, but we would more than likely hire someone to take over that part of the company so that development can continue without us going absolutely insane.
Note: As of September 12th 2019, we no longer provide official support for our Anki based pronunciation trainers and word lists. You are more than welcome to still purchase and use them, but the support we are able to offer for these products is limited. For supported languages, these materials are already built into the Fluent Forever app.
