Could you share the rationale ? Harmattan is still going to be Maemo under the hood, Moblin 2.2 is still good old Moblin under the hood, so the best we can talk about is actually how easy it will be to transfer applications, development, etc between 'mainline' MeeGos and these 'work-in-progress' MeeGos, but that does still not help differentiating them. For example, how do you explain the difference between the LG GW990 and the future Harmattan device to someone ? Both claim to be MeeGo phones (or mobile computers) but - they have separate architectures, separate UIs, separate (but similar) APIs, separate package management, separate appstores/repositories, separate upgrade paths... you get the idea - there's just too many loose ends with the current transitional devices to be able to get away with calling them all MeeGo, no matter how tempting that may be from a marketing perspective. You'll just end up diluting the MeeGo brand, as it won't matter if something is MeeGo or not, but rather which exact device you have, which does not bode well for the platform (by either the weak branding OR the fragmentation it foreshadows).
