The TV and mobile-device OEM OnePlus has hinted at a "special project" with an intriguing trailer via its UK division's Twitter account. However, like the Concept One, it is not a product that will go on sale soon, although the company still wants public feedback for it. It is to be revealed on March 3, 2020 (or tomorrow, in other words).
