Nokia appears to be sticking with the Lumia brand for its upcoming Windows RT tablet. Twitter account Evleaks, who has accurately predicted various Nokia devices in the past, claims the Finnish smartphone maker will select Lumia 2520 as the final name for its "Sirius" tablet. Nokia's Windows RT tablet was recently pictured alongside other new Windows 8.1 devices, and evleaks expects the company to announce it on October 22nd.

The Lumia 2520 is a 10.1-inch tablet with a quad-core Qualcomm processor and 1080p display. It will be Nokia's first Windows RT-based tablet, and is expected to debut for $499. Nokia is also planning to release a battery-equipped keyboard accessory for its Lumia 2520, allowing owners to boost the main device battery through the keyboard. Despite Microsoft's recent acquisition of Nokia's phone business, it appears the company's tablet is still going ahead. Nokia is also expected to unveil its 6-inch Lumia 1520 smartphone at its mysterious event next month.
