Microsoft has unveiled its new Xbox, setting the stage for 2020 console war with Sony. The Xbox Series X comes with a peculiar monolithic design, almost resembling a PC tower. Microsoft didn't disclose a price but said the Xbox Series X will go on sale in the holidays next year. Microsoft hasn't shared all the details, but it said the console will be able to deliver four times the processing power of the current Xbox One X. The Series X will provide "world-class visuals" in 4K at 60 frames per second and up to 120 FPS being a possibility, according to Microsoft. And the console will "virtually eliminate load times" thanks to its graphics processing unit and solid-state drive. The decision to go with a powerful-yet-large design is the opposite of what rival video game maker Nintendo has done with its Switch. The relatively small console can be played while plugged into a TV or on the go, and Nintendo recently boasted that it had sold more than 15 million units in North America and has been the best-selling video game console for 10 consecutive months. The Series X's power could be key for Microsoft in the competition for gamers' attention and sales. Sony's PlayStation 5 is also due to release next year. Sony has kept mostly quiet about its upcoming console, but it has promised technical upgrades to improve performance.
