From the first glance, it'll be using Xorg, not Wayland, but that's still very good, since it'll allow a natural Qt usage there, and with it being a conventional Linux stack with drivers available, Mer ports to Tizen devices should be possible. So far so good - let devices come now.

Not sure if it belongs to general, or rather this category (Meego/Harmattan). I don't really read other parts of Maemo Talk :) (Got enough to follow a bunch of subjects here and on Meego forum). If Tizen is viewed as Meego successor, you can just rename it to Meego/Harmattan/Tizen ;)
