If you thought nothing about Google TV was going on at Google I/O this year you are mistaken. Although they didn't mention anything specific to Google TV during the keynote, since then they announced some cool new things for the service. First, Google is now sending out the latest Android 4.2.2/Jelly Bean to Google TV. This is a welcome upgrade and should get GTV users excited. Additionally, they are also sending out the latest version of Chrome as well. Now browsing on your Google TV should be even faster than before.

That's not all. Google also announced they plan to bring updates to Google TV on a much more timely basis, specifically stating “weeks rather than months.” Here's a quote below from the Google TV developer's blog G+ account with all the details,

Over the past few months Google TV has gathered momentum by launching powerful features for our users such as the highest quality voice search of any TV product and strong manufacturer adoption of the platform. At Google I/O, it’s time to talk about developers and enabling them to bring more great experiences to TV.

Today, Google TV is moving to the latest version of Android (Jelly Bean, 4.2.2), and we’ve refactored Google TV so that our TV OEM partners can update to future versions of Android in a matter of weeks rather than months. For developers, this means you can build TV experiences using the latest Android APIs, including the NDK.

Today Google TV is also moving to the latest version of Chrome, and from now on Google TV benefits from Chrome updates on the same six week cycle that you’ve come to expect from Chrome. In Chrome on Google TV, we’ve added support for hardware-based content protection, enabling developers to provide premium TV content in HD within their web apps.

Google TV-powered devices in market will start to receive updates in the coming months, and we expect to see new devices launched later this year. If you are attending Google IO, please check out the “Android: As seen on TV!” session and stop by the Google TV Developer Sandbox area.
LG has already updated some of their new Google TV equipped LG HDTVs with the newest Android 4.2.2 version. Above is a video of the TV with the new update.
