Devs are working hard on Catapult. They don't post a roadmap. More like updates on what has been done. https://forum.nem.io/t/stories-from-the-dev-front-diary/2641

The great things is on the backend, we have three professional and full-time devs working very hard, making a completely new system that hasn't been done before.  They already broke a lot of ground and made a long line of firsts that we have with the current version of NEM, and the next will be a lot better.

I realize that people want a roadmap to be very clear, but instead what is offered is a list of accomplishments. That is more or less the opposite of the pump and dumps on this site.
