Tizen basically limits development to web apps and the Samsung SDK agreement signs all your rights over to Samsung (unless something changed recently). Because of Samsung's strong-armed control over a "Linux foundation project", nobody wants to touch it (Meego was way better in that regard -- Intel and Nokia have much better corporate culture regarding open source projects). FirefoxOS had some potential, but the Firefox guys killed it and it was often viewed as bad Android (probably due to only shipping on crappy devices). A premium phone with webOS could be a device that has the benefit of web apps, with the fallback of native (a big feature for a lot of important apps) with a compelling UI.
