The controversial Russian blogger Eldar Murtazin posted a tweet claiming the Tizen OS (http://blog.gsmarena.com/samsung-tizen-2-1-screenshots-appear-show-how-far-the-html5-based-os-has-gone/) is almost dead. He also suggests Samsung won't release more than one device running on Tizen.
Tizen is almost dead. It isn't delay. That's cancel of the whole project. I doubt that samsung will launch more than one device for 2014
