We've known about Google's Nest Hub Max for quite some time, seeing it pop up sometime in March and later being announced during its I/O Developer Conference. It looks like for a brief moment, Google had plans to release the device on September 9 before pulling the date from its support page.
As first reported by Droid Life, Google made the September 9 date available through its support page, showing that it would release the device in Australia, the United Kingdom, and the United States. Revisiting the support page, it currently shows the date has been pulled and it has reverted back to its "coming soon" status.
For those unfamiliar with the $229 Nest Hub Max, it is essentially a larger version of the Nest Hub, and offers users a different way to interact with their Google data. It is unknown at this point when Google will release the Nest Hub Max, but if you are interested, you can head to the product page and sign up on the waiting list. If Google is looking to stick its original plan of releasing it before the end of summer, time is ticking, with only a couple of months to go.
