Samsung was originally supposed to launch the Samsung Z in Russia last year, followed by a European roll-out, but that launch got delayed. Fast forward to today and the latest rumour is that Tizen Mobile is still being tested across some of the large European countries. According to Information from Sammobile, the device might be the Samsung Z or the soon to be released Samsung Z3.
There is also news that it will be running Tizen 3.0, but that really depends on when it will be released and assuming the launch schedule is for next year, then it might as long as their is enough development effort applied to it by Samsung.
In-line with Samsung's new Tizen mobile strategy releasing in Europe will not be considered until more emerging markets are tested and hopefully conquered. We also need a more robust app ecosystem to take on the European smartphone market. Anything is possible, we just need copious amounts of money thrown at it.
