Today Tot released an article regarding this year's projects.
Wakfu S4 is looking good, but nothing has been signed yet. FranceTV seems on board and he'll have a meeting with them at the end of this month. Netflix is an important piece, so he's hoping the Worldwide release on April will do good.
On the other hand, he has confirmed that he's working on a comic telling Oropo's story, and how he got the Eliacube. It features his last Eliotrope friends and a younger Echo. It was supposed to be a special episode like Nox's was, but the budget for it would be too big so they went for a comic instead.
