Branded the Nexus 7, the device as described by Gizmodo features a seven-inch screen, a 1.3Ghz processor, a 12-core GPU and 1gb of RAM, and is built by Asus.
The Nexus brand is known for featuring the latest, purest form of the Android OS
The tablet is set to be priced at around $200 for a model with 8gb of hard drive space.
That would price it to compete with Amazon's Kindle Fire tablet, which itself runs a (highly modified) version of Android.
The announcement, if it comes, would follow the unveiling by Microsoft of its own first-party tablet, the Surface, which runs Windows 8, and Apple's new version of the iOS operating system.
However, Gizmodo added that it was still possible the leak was part of an elaborate fake - and that it was still possible a different, or no, tablet could be released at the I/O conference.
