The third-generation Chromecast is the star of a new sighting, this time in a bundle called the Smart TV Kit along with the already known Google Home Mini.
The image you have seen above was posted on Reddit by the employee of an electronics store whose name is not yet known. It can be assumed that this is the Walmart chain, which also had the exclusive Kit including the second generation Chromecast.
Although the photo looks real, there is no further information related to this bundle. It will be necessary to wait for the Google event to be held on next October 9th. Recall that, in addition to the new Google Smart TV Kit bundle, will be announced the Pixel 3 and Pixel 3 XL smartphones, the Google Home Hub smart display, and the alleged 2-in-1 notebook with Chrome OS.
