Nvidia appears to be taking its Android-powered portable Shield from mobile phone-sized devices to tablets, according to a filing with the Global Certification Forum validating the new device's wireless connectivity.
In a related tweet on Monday, the device is called a "Notebook/Tablet," perhaps indicating a dual function or convertible form.
The Verge, which spotted the GCF filing, notes that the Shield Tablet was alluded to in both an earlier submission with the Federal Communications Commission and even the appearance of the product's name on the Nvidia website.
Polygon has contacted Nvidia for comment on its plans and will update this story with any response it makes.
The Nvidia Shield launched on July 31, 2013, and it delivered a substantial update to its operating system in early April. For more on the device, see Polygon's preview of that update.
