Look, our time to start discussing Harmattan in more detail comes with the Harmattan alpha release. Think of it: makes sense. In the meantime Nokia representatives are encouraged not to make promises or especulate, which also makes total sense. Maemo 5 has a roadmap of updates that includes more than bugfixes. It hasn't been disclosed, but the plan exists and is being executed as we speak. No matter what you think today, I bet by the Harmattan alpha release your thoughts will be different based on the new information we will have shared with you. In the meantime, trust me: the value and usefulness of this thread beyond (say) the post 100 is arguable to say the least.
And for you to consider: if setting "Harmattan" target milestone in maemo.org bugs and brainstorms causes all this especulation, bad mood and anxiety then you are making it easier for someone to tell us (Nokians active in maemo.org) to stop sharing any Harmattan related information, for the good of the N900 customers. Threads like this one wouldn't help us defending the increase of openness beyond the scope of open source projects..
