I think you're mixing UX with the technologies the UX is done with (UX vs UX framework, the result vs the tools). I'm quite sure Nokia's real MeeGo devices will have pretty much the same UX as the Harmattan N9. Nokia isn't discouraging developers developing for that UX, they're encouraging developing for that UX with a more future proof and cross-platform tools. Just speculation, but I find it hard to believe that they'd scrap all MTF and Orbit applications they've already done. I think the plan would be to maybe migrate them to Qt Quick while already using that for new development. What you refer to as Intel MeeGo is the vanilla MeeGo(it's the same on Intel and ARM). It's even worse on the Aava(x86 reference handset) than it is on the N900 at the moment. N900 is the only device with MeeGo where you can do a phone call at the moment.
