The Echo, which went on sale in 2015, will grab 63% of the USA market this year, according to EMarketer.
Better audio means not only being able to charge more for the unit, but an ability for Amazon to better compete with the likes of the Apple HomePod and Sonos One. Google has done quite well for itself with a market share of 31 percent. The very same cameras would likely also turn the device into a mobile Ring video camera, which would alert users of any nefarious going-ons while the robot patrols your home.
Vesta is reported to be a bout waist-high, with wheels and an array of cameras that use computer vision to navigate the device. We shouldn't expect this new Echo to appear before the end of 2019, but it could never see the light of day if Amazon decides tweaks to its existing line-up are enough when they inevitably get refreshed.
Amazon is still working on a robot that will roam around homes, according to Bloomberg.
As noted by CNBC, Amazon typically releases its biggest products in September at its Seattle headquarters.
We reached out to Amazon, but a spokesperson said the company does not comment on "rumours or speculation". We should also expect a high-end Echo smart speaker to launch in the near future. Bloomberg reports that while the robot isn't ready for mass production, Amazon recently brought in engineers from other projects to work on it, suggesting a push for commercialization.
That new Echo is bigger than what we've now got in part because it needs space for more hardware. The company has in the past introduced a standalone subwoofer and connections to link the speakers to home stereo systems.
