Guys, it's not that difficult. This thread is about Harmattan (Maemo 6 core + Nokia hardware adjustments + UI & applications from Nokia), period.

The Harmattan UI Framework is open sourced and it's already been renamed MeeGo Touch UI Framework. I assume the Linux Foundation reference Handset UI will utilize this same framework as Harmattan. Linux Foundation's reference UI + applications should be open source. Nokia can replace some of these with closed source equivalents in their own products if they so choose.
