This article, Following Xbox One, PS4 Getting Twitch App This Year, originally appeared on GameSpot.
Today during the the keynote address at the first-ever TwitchCon conference, Twitch CEO Emmett Shear announced that a Twitch app is coming soon to PlayStation 4, PlayStation 3, and PlayStation Vita.
The app is due out this fall. Twitch functionality is already baked into PS4 through built-in streaming that's available by pressing the DualShock 4's "Share" button. But the new app will let users watch livestreams (those from PS4, PC, and all other platforms) and use full chat functionality (including emotes).
The app was shown off during the TwitchCon keynote today and it looks a lot like the Xbox One version, which has been available since 2014. It will launch first for PS4 in October, followed by PS3, PS Vita, and PlayStation TV.
In other recent news, a Twitch app is coming to Oculus, letting you watch game streams and other content in virtual reality. Twitch was acquired by Amazon in August 2014 in a deal worth $1 billion.

I'd really like this if we are able to watch Twitch streams other than PS4 ones. I'd like to watch some League of Legends Twitch stream.
