Yes there's a video about a UI that have not even said to be vanilla MeeGo tablet UX. There's no bug reports, no announcements and while the meego.com got slot for TV, phone, netbook, in-vechile and media phone, there's nothing about tablet UX.
It might be running MeeGo but real MeeGo tablet UX...

Just compare it to netbook and handsets weekly builds and what not that we have been getting for long time.
