Here's everything we expect Google to announce at its biggest hardware event of the year

If the device obtained by Engadget is, indeed, the Pixel 3, we now know that the phone will come with a wired, USB-C version of Google's Pixel Buds.

This is noteworthy, as the Pixel 2 smartphones didn't come with USB-C earphones, despite the fact that Google ditched the headphone jack.

Few rumors exist on the Pixel Buds 2 wireless earphones, but the general consensus is that Google will announce new Pixel Buds at its October 9 event.

We're hoping that a new set of Pixel Buds will bring substantial improvements over the originals, which weren't well received at all by critics, including Business Insider's own Avery Hartmans.

The new Pixel "Slate" by Google is said to be a Chromebook tablet designed to be attached to a separate keyboard. Tech blog MySmartPrice, which has accurately leaked Google products in the past, obtained the photos and details about the new device.

It's a similar form factor as Microsoft's Surface Pro tablets, which can be attached to a keyboard. The Pixelbook Slate's keyboard will feature a touchpad and round keys, and the tablet itself is said to have a camera on the front and rear, and a power button with a built-in fingerprint sensor. The Pixelbook Slate will also reportedly be compatible with an active stylus.

The other Chromebook may take on a more traditional laptop design — it could even be the direct successor to the original Pixelbook, which launched in 2017.

We don't know much about the new Chromebook, but it is said to come with a 4K display, according to Kevin Tofel from AboutChromebooks.

Google may also announce a new smart screen device called the Google Home Hub, which will essentially function similarly to Google's Home smart speakers powered by Google Assistant, but with a 7-inch touchscreen.

The device is pretty straightforward, based on the leaked documentation obtained by MySmartPrice: You'll get the information you've always received from Google Assistant — like the weather, calendar events, commuting information, news, and any other useful data — with the added bonus of seeing the information, rather than simply hearing it.

Google's Home Hub wouldn't be the first device with a screen that has Google Assistant built-in — Lenovo has a smart device called theLenovo Smart Display. If you want an idea of what Google's Home Hub will do, checking out Lenovo's device would be a good place to start.

This leak has an unusual story: According to Android Police — which first spotted the report on Reddit — a Best Buy customer was able to buy an unannounced and unreleased model of Google's Chromecast media streaming device a full nine days before Google's event.

The Redditor said the Best Buy cashier at first wasn't able to scan the device because it wasn't in Best Buy's system yet. It showed a release date of October 9 — the same day as Google's upcoming event.

The new Chromecast appeared to have the same price as the previous generation Chromecast, so Best Buy rang it up as an older Chromecast and sold it to the Redditor. Unfortunately, the Redditor wasn't able to start it up, as it required a Google Home update that isn't available yet.

Apart from its slight redesign, we don't know what new features it might have.
