Samsung is known for its ubiquitous Galaxy smartphones and tablets, popular smart televisions and, most recently, smartwatches. The Korean consumer electronics giant is about to enter another major new category: virtual reality headsets. We're told by sources close to Samsung that a virtual reality headset is not only in the works at the company's mobile division, but it's set to be announced this year. The urgency is said to be a measure of beating Facebook's Oculus Rift and Sony's Project Morpheus to market. Some developers already have early versions of the headset, which -- at least in the development stages -- is powered by flagship Galaxy devices (think: Note 3, Galaxy S5). The consumer model, however, is said to require the power of next-gen, unannounced Galaxy phones and tablets.
