Google set to show off a new version of its Chromecast media-streaming device later this month, according to 9to5Google. Documents reportedly obtained by the site indicate that the second-generation Chromecast will have upgrades over the current version, including improved Wi-Fi, and a slate of new features. Among those additions are support for content feeds, and a new feature called "Fast Play" which could make connecting Chromecast to other devices quicker and simpler than it has been in the past.

Pictures of the updated device are small and blurry, but seem to show that the new Chromecast will keep the same dongle shape as its predecessor, and will be available in a variety of colors. The images also show something called Chromecast Audio, which, according to the documents, will allow your Chromecast to connect to speakers via auxiliary cord. 9to5Google says Chromecast Audio will have multi-room support, will be able to mirror your Chrome or Android audio, and will boast "high-quality" sound.

There's no exact details on what the support for content feeds, Fast Play, or the improved Wi-Fi will bring for the second-generation Chromecast, but it seems we won't have to wait long for official specifications: the new Chromecast is reportedly set to be announced at Google's event on September 29th. At the same time, the company is expected to reveal two new Nexus phones — one from LG, and one from Huawei.
