The 7 biggest announcements Amazon made at its Echo event, from a mini drone that can fly around your home to a cloud gaming service

Amazon took the wraps off Luna on Thursday, marking its long-expected entrance into the cloud gaming space. Amazon is letting the public sign up to request early access beginning immediately. The service will be available on iOS, Android, Mac, Windows, and Fire TV.

The service will encompass multiple channels, including a Ubisoft channel and a Luna+ channel, the latter of which is available for $5.99 per month during the early access period. Amazon also designed its own controller for Luna that connects to the cloud rather than your device, which the company claims should prevent latency and pairing issues.

No more cylinder or hockey-puck shaped speakers from Amazon. The company introduced a completely redesigned Echo lineup that features a uniform, spherical aesthetic across its main Echo and Echo Dot devices.

The new Echo will also inherit some features from the pricier Echo Plus, such as its built-in smart home hub. The new Echo will start at $100, while the redesigned Dot version begins at $50 and the Dot with a digital clock display starts at $60.

Amazon also announced the $200 Ring Car Cam, a security camera for the road that can keep an eye on your car whether its parked or in transit.

The camera comes with a feature called Traffic Stop, which enables it to record an interaction with police and alert designated contacts after the user says "Alexa, I'm being pulled over." The device can also surveil your car while it's parked to check for at temped break-ins or other unusual activity.

The camera can also request help from first responders when necessary while driving.

The launch comes after Ring's partnerships with hundreds of police departments across the United States has drawn scrutiny from civil liberties activists, privacy advocates, and lawmakers.

The Ring Always Home Cam is designed to do what its name implies: make it feel like you're always at home by keeping tabs on your house while you're away.

The Always Home Cam is essentially a tiny drone that can autonomously fly around the house, enabling it to monitor multiple areas without investing in multiple cameras. Users must set a predetermined path for the Always Home Cam to follow. So if you want it to check whether you left the stove on, for example, you'd have to create a path to the kitchen.

The device sits on a charging base that also blocks its camera when not in use.

It's not just the standard Echo lineup that received an upgrade on Thursday. Amazon is also refreshing the Echo Show with a new 10-inch model that has a rotating screen that can follow you around.

When you're on a video call, for example, the Echo Show can move so that its 13-megapixel camera can keep you in frame. If you have Amazon's Alexa Guard feature turned on while in Away mode, the Echo Show can also pan around the room to look for disruptions.

The new Show costs $250 and starts shipping later this year.

Amazon also unveiled some new features that make Alexa better at holding a natural conversation.

In a demo, the company showcased a capability it calls "natural turn taking," which allows Alexa to chime into a conversation when summoned. During one example, Amazon showed how Alexa could offer up pizza specials from your favorite place after telling it that you want to order pizza.

The company also announced a new feature that enables Alexa to ask for clarifying information when the assistant isn't sure what the user is referring to in a request.

Amazon also unveiled a $40 Fire TV Stick that it says should get a 50% speed boost compared to its predecessors as well as a cheaper $30 model called the Fire TV Stick Lite.

It's not just the hardware that's getting an update. Amazon is also rolling out a more personalized software experience for the Fire TV that should make content easier to find and offers new Alexa features.

Last year's event was all about experimenting with new form factors for Echo devices, like the Echo Loop smart ring, Echo Frames glasses, and Echo Buds. But this year, Amazon dove deeper into the product categories it's been expanding into for years, such as the smart home, security, and entertainment.
