From the leaks I've seen samsung is turning tizen into touchwiz, just like bada. If this doesn't change I really don't care, yeah open sorce, but with that horrible gingerbread looking UI is not something to continue. They were an early look, but nothing interesting. I saw videos showing cool graphics, but they were cool graphics for the sake of it and not for function.
