Samsung hasn't slowed their move off of Android at all. This winter, they released the new Gear 2, which ran Tizen instead of Android. Earlier this month they released details on their new Z phone, their first phone to run Tizen. In addition, they announced that they're moving to Tizen for their smart TVs.
They're still trying to move to Tizen as fast as they can; it's just taking time for them to get there.
Samsung doesn't seem to believe Tizen/Android is an either/or situation. They shipped a Tizen watch and now are shipping Android watches. They are actively developing Android and Tizen phones, and it wouldnt surprise me if they shipped the new Google TV.
Samsung will try anything and go with what sells. Many see this lack of strategy as a weakness, but in some ways it's also their biggest strength.
