Google's Nexus 9 tablet and Nexus 6 smartphone are expected to be announced on Wednesday (October 15), Digital Spy said.
Both devices will apparently run the Android L operating system, with the company likely to make the double announcement through a blog post rather than a big launch event.
Forbes reports that the HTC-made Nexus 9 will be released on November 3.
The Nexus 9 will cost $399 for the 16GB version and $499 for the 32GB LTE version, and will be the first device to run Android L.
Previous reports suggest that the Nexus 6 will feature a 2560 x 1440 resolution screen, a Snapdragon 805 processor, 3GB of RAM, a 13-megapixel camera, 32GB of storage and a 3200mAh battery.
Both devices will have expandable memory.
