Samsung just posted a new flyer calling the global developer community to get an early access to the software development kit of the company's next-gen Gear device. From the invitation, it's pretty clear the new device will be round:
Samsung's upcoming Gear device will be a smart watch - and will be Samsung's 6th generation Gear (which is pretty amazing considering that the company's first-gen Gear was released less than two years ago).
It is not surprising Samsung is adopting a round display this time. We've seen several such watches (including the Moto 360, LG's G Watch R, Huawei's Watch and others) - and most consumers seem to prefer the classic round watch design. It's highly likely that Samsung will adopt a circular flexible OLED display, which will be the first such display produced by SDC.
