The still unannounced Z1 is Samsung's latest, perhaps its last, hurrah to get the Tizen platform on a smartphone. Already delayed by a few weeks, at least based on initial rumors, the smartphone has now been spotted in a few press materials not yet meant for public eyes. But we've seen this before and we've seen press materials before, even official ones. None of which mattered in the end. The biggest question on everyone's mind now is "when" (perhaps other than "why").
