A slide from Intel Developer Forum says "Core M2 Handset UX, based on Intel UX design(using handheld UI framework)". The framework is Nokia developed, but that line leads me to believe the rest of it is not strictly a Nokia effort. Nokia can, and has in the past kept certain built in applications closed(differentiation). MeeGo reference UX being 100 % open, it's a no go for those and something else is needed there. And the bug reports against the handheld UX also seem to indicate Intel developers working on the applications. Maybe I'm just reading way too much into everything, but I guess we'll see once the reference and Nokia UX's are out..
