Amazon sent a mysterious invite out to UK publications this morning, hinting that the company might be about to launch its popular Echo voice-controlled speaker in Britain. Amazon originally launched the Echo in the US last June, but has not yet made it available in Canada or internationally. The company's invite doesn't drop too many hints, but if you ask Alexa (Echo's voice assistant) what's happening on September 14th, you get a good idea.

"I promised I wouldn't tell," replies Alexa, in a video posted by Engadget editor Matt Brian. "A visit to London has always been on my bucket list." The press invite comes just weeks after a blogger found that Bing was caching a mysterious URL on Amazon's UK site for Echo preorders with a September 16th release date. That caching might have been a mistake for another product, but Alexa is clearly dropping hints we'll see the Echo launch internationally for the first time since its debut last year. The Verge will be covering Amazon's UK event, so stay tuned for more information on September 14th.
