I just accessed the Twinmotion Roadmap page and noticed this too. I'm a little disappointed. I expected the new vegetation models to arrive this year for Twinmotion...
Other items were also moved from "in progress" to "under consideration".
Thank you for posting in the community and for your keen eye to our road-map. We are still planning on providing more vegetation content and recommend you provide this feedback directly on the road-map tile as this goes directly to the management team.
