Amazon will hold a hardware event on Thursday, September 24. According to The Verge, the event is for invitees only, which presumably also means there will be no livestream of the presentation.
Despite seemingly no livestream, it can be assumed that the invited media will announce the content of the presentation. What Amazon will show on Thursday is also not yet announced. No doubt because of the coronavirus, the presentation will be given virtually.
At previous events, Amazon showcased smart speakers and displays such as the Echo Studio and the Echo Show 8. However, it may also involve more experimental hardware, such as the Echo Frames and Echo Loop, which the company came up with last year. They are not available to the general public.
