The Duo 11 is seen as a direct competitor for Microsoft's upcoming Surface tablet in both configuration and price, Slash Gear reported Thursday.
Most Duos will feature Intel's Core i7-3517U processor although a few lower-power, lower-price CPU options are expected to be available.
RAM options are 4 gigabytes and 8 gigabytes with 128 or 256 gigabytes of storage through solid state drives.
An 11.6-inch display, a stylus for input and front and rear cameras round out the hardware specs.
Expected in late October, Sony is remaining mum on any pricing policies, Slash Gear said.
