Update: Samsung is expected to launch the Galaxy S9 and Galaxy S9 Plus on February 25 at MWC 2018... could there be another smartwatch on the way alongside the new phones?

We've been anticipating a device called the Gear S4 for over a year and a half now, but instead Samsung introduced us to the Gear Sport at the tail end of 2017 and it's currently uncertain what the next smartwatch from the company will be called.
