Mashable: Most of them are available for preorder immediately.

Amazon revealed a massive wave of new Alexa-enabled devices during its annual Devices & Services Event livestream Wednesday, including a new Echo Show 8, an Echo Pop Kids, 10-inch Fire Kids tablets, Echo Frames, a Fire TV Soundbar, two Fire TV Sticks, an eero mesh router, and a new Blink security camera (plus accessories).

Whew.It's been a big week for Amazon: In addition to the new Amazon devices, the tech and retail giant announced Monday that it will be kicking off the holidays early with a second Prime Day sale from Oct. 10 through 11 (renamed "Prime Big Deal Days" from last year's "Prime Early Access Sale"). This is great news even if you're not interested in any of the new hardware, as Amazon will probably use it as an excuse to deeply discount older models.

Here's a rundown of each new Amazon device's pricing, specs, and preorder details:

Alexa and Echo devices
Amazon Echo Show 8 (3rd Gen)

Billed as Amazon's "most ambient device yet," the third-generation, eight-inch smart display is now a smart home hub and a smart speaker with spatial audio and "room adaption" that optimizes sound based on the acoustics of its surroundings. It can also change the interface of its home screen based on your proximity to it. It's powered by an updated processor with faster response times, and it has a centered, auto-framing 13MP camera and mics with noise-reduction technology for improved video calls.

The new Echo Show 8 is priced at $149.99 (or $20 more than its predecessor) and is set for release on Thursday, Oct. 26.

The kid-friendly version of Amazon's cutest smart speaker comes in two colorful designs: Marvel’s Avengers and Disney Princess. Both include parental controls and six free months of Amazon Kids+.

It's available for preorder for $49.99 ahead of its release on Thursday, Oct. 26.

The new Fire HD 10 Kids is geared toward little tykes ages three to seven, while the new Fire HD 10 Kids Pro is geared towards youngsters ages six to 12. Both tablets are lighter and faster than their predecessors, with 10.1-inch 1080p displays and up to 13 hours of battery life. They come with a year of Amazon Kids+ as well as a two-year worry-free guarantee.

The new Fire HD 10 Kids and Fire HD 10 Kids Pro start shipping on Thursday, Oct. 19 and sell for $189.99 apiece, which is $10 less than the previous generation.

Amazon's revamped lineup of Alexa-powered eyewear comes in seven frame styles, including two designed in partnership with Carrera Eyewear, a high-end Italian brand. They're scratch- and water-resistant and come with multiple lens options, offer up to 14 hours of battery life with moderate usage, and support multipoint pairing.

The new Echo Frames will start at $269.99, a $20 price bump. They're not available for preorder yet, but interested customers can sign up to get notified when they're released.

Fire TV devices
All Fire TV streaming devices and smart TVs (both new and older models) include a six-month free trial of MGM+ starting immediately.

Amazon Fire TV Soundbar

Compatible with all Fire TV media players and TVs, Amazon's new 24-inch, Bluetooth-enabled soundbar supports DTS Virtual:X and Dolby Audio.

The Fire TV Soundbar is priced at $119.99 and available for purchase immediately.

Amazon Fire TV Stick 4K (2nd Gen)

The upgraded Fire TV Stick 4K brings support for WiFi 6 and packs a 30% faster processor.

It's available for preorder for $49.99 (the same price as the 2021 model) and formally launches on Wednesday, Sept. 27.

Amazon said its next-gen Fire TV Stick 4K Max is the first streaming stick to support WiFi 6E. It also comes with the Fire TV Ambient Experience (previously exclusive to last year's Fire TV Omni QLED Series TVs), meaning it can replace any blank TV's display with artwork à la Samsung's The Frame.

Set for release on Friday, Sept. 29, it's available for preorder for $59.99. That's $5 more than its predecessor.

Smart home devices

This wall-mountable command center has an 8-inch touch screen and customizable dashboard where you can control all of your smart home devices, including lights, speakers, and home security cameras.

The Echo Hub will retail for $179.99 when it debuts later this year. You can sign up to get notified when it goes live via its product page.

Amazon eero Max 7

Amazon's first WiFi 7 mesh system, which doubles as a smart home hub, can deliver wired speeds of up to 9.4Gbps and wireless speeds of up to 4.3Gbps.

It will come in one, two-, and three-packs starting at $599.99 once it's available. Customers can sign up for email notifications in the meantime.

Home security devices
Blink Outdoor 4 Floodlight Camera (and Floodlight Mount)

The latest iteration of this wireless smart security floodlight from Blink, an Amazon-owned home security company, has motion-triggered LED lighting and a battery life of up to two years.

It's up for preorder for $159.99 (a $20 price increase from the previous model) before it arrives on Tuesday, Oct. 17.

Customers who already own a Blink Outdoor 4 will be able to turn it into a floodlight camera using its new mount accessory. That's priced at $39.99 and starts shipping on Wednesday, Oct. 18.

Blink Sync Module Pro

The Blink Sync Module Pro is a new system hub for Blink devices that can store video clips locally (via MicroSD card, sold separately) and extend Outdoor 4 cameras' range up to three times beyond that of regular WiFi.

It's priced at $49.99 but isn't officially up for preorder yet; customers can sign up to get notified as soon as it's available.

Blink Battery Extension Pack

This compact battery pack boosts the already impressive battery life of a Blink Outdoor 4 camera (sold separately) from two to four years.
