Nokia has never made an official statement and I don't know what discussions they've had internal. I can only reference what I've seen on TMO and it has been discussed here many times and apparently some still want to see it happen.

Personally I think they should kill Fremantle and Harmattan and give full access to changes, both firmware and base apps to the commuinity.

Force an upgrade to Meego 1.0 ready or not, with official support but those that love the Maemo way they can continue to hack until their blue in the face. No ambiguity. Meego = support. Maemo = hackfest.

I see no reason why Harmattan should be productized with Meego on the horizon (and forget the branding) and personally I want to see who can make a better OS, the community with Maemo or Nokia and Meego! Let the better man win.
