Nokia is planning to launch its first Windows RT tablet in September. Sources familiar with Nokia's plans have revealed to The Verge that the company will unveil its tablet at a special launch event in New York next month. Nokia has been courting developers for the event, and it's tentatively scheduled for September 26th. We understand that Nokia will unveil a tablet, currently codenamed Vanquish, that features Qualcomm's quad-core Snapdragon 800 processor and Windows RT. Nokia's tablet will include LTE support, and will be made available on AT&T in the US.

Alleged photos of what appears to be a Verizon variant of Nokia's tablet leaked to Chinese site Digiwo today. The photos show the rear of a red 10.1-inch tablet with the Verizon, Windows RT, and Nokia logos. The size and logo placement are consistent with genuine photos of Nokia's canceled Nvidia-powered tablet. Nokia was originally developing that particular Windows RT device with a unique battery-equipped keyboard cover. It's not clear if the latest Qualcomm-based tablet includes the cover, but we'll likely discover this and a lot more during Nokia's event next month.
