Google’s big hardware event, scheduled for October 9, is expected to feature the new Pixel 3 and Pixel 3 XL phones. But now we know that Google will probably reveal a third-generation model of Chromecast, thanks to one recent Best Buy customer who discovered the device on store shelves.

Whoops.

“GroveStreetHomie” detailed his experience on a Reddit post entitled “I think I bought the 3rd gen Chromecast too early.”

According to the Reddit post, the customer went to Best Buy earlier to pick up a Chromecast for a new TV. That’s when “GroveStreetHomie” noticed the packaging and design was different from an earlier version.

The cashier wasn’t able to scan the item because it wasn’t in the system yet. The release date was labeled October 9 — the same day as the 2018 Google hardware event.

“But since I already had it in my hand and was the same price as the 2nd generation Chromecast, they let me have it under the old SKU,” the post read.

This new unannounced Chromecast is apparently thicker than the second-generation model. The Chrome logo has been replaced with Google one. The new device still has a micro-USB. The HDMI connector on the tip and base has been removed, according to the user.
