The information comes from Evan Blass, better known as @evleaks, confirming that the device will be released before the end of the year. While there is no more information, the lack of the Nexus brand in the Tweet suggests that Google might have completely killed the Nexus brand and will focus on the new Pixel brand, as previously rumored.
There is not a lot of information regarding the device, other than it will have a 7-inch screen and come with 4GB of RAM.

The same 7-inch successor of the 2nd-generation Nexus 7 has already been teased earlier as Huawei has already trademarked the device as the 7P, which kicked off rumors that the device might end up with a Google Pixel 7P name.
There is a rumor that Google will be hosting an event on October 4th, where the company may unveil two new smartphones, rumored as Pixel and Pixel XL, as well as the new Chromecast device, but it is still not clear if it will be the event for the new 7-inch tablet as well.
Hopefully, we will hear more as we draw closer to the end of this month.
