We haven't been very forthcoming about the content being created for the next releases of maemo 5. I can assure you, there is a lot of great content being developed, and you should be able to get your hands on it soonish. Roadmap page is a great idea in my opinion, the only issue being in it the dates, which we don't want to commit to. But I'm sure a roadmap can be built without such. I'll take the action of following that up.
