Just a few weeks ago, Pandora became the latest app to receive support for streaming via the Chromecast, as did Hulu Plus just before that. This left a couple of key holdouts, one of which being HBO Go. HBO Go has been rumored as coming to the Chromecast since the device’s launch, with HBO confirming earlier this summer that it was in talks to support the Chromecast in the “future.” It now looks as if the launch is not very far off.

As first noted by Droid Life, Google’s “Now Casting” support page has been updated to include HBO Go. It’s touted as a “new” app, along with Pandora and Hulu Plus. Oddly, however, there is no HBO icon and the description simply reads “none.” This makes it seem like Google’s support page was updated a bit prematurely, although it does signal that a launch is imminent and that the two are still in talks to work together. We wouldn’t be surprised to hear an official announcement from Google and HBO relatively soon.

In order to support casting content to Google’s Chromecast, the HBO Go iOS app will have to receive an update as well. So we’ll be on the look out for that, too.

At $35, the Chromecast is becoming even more enticing of an offer as Google continues to beef up the streaming selection to compete with the Apple TV and Roku. The casting feature is nearly identical to Apple’s AirPlay, so as more content is supported, it’s becoming harder and harder to justify the price difference between the two.
