Sony announced a new handheld gaming system this week that it claims will revolutionize the portable entertainment experience.

The new PlayStation Vita was unveiled as part of Sony’s presentation on the eve of the Electronic Entertainment Expo in Los Angeles.

The Vita marks Sony’s biggest advance in the handheld gaming space since it introduced the Sony PSP in 2006. The Vita doesn’t feature 3D gaming, like rival Nintendo’s 3DS, but the dual cameras will be used in another emerging video-game space — augmented reality.

The unreleased PlayStation Vita is already generating more buzz than the established Sony PSP.

Sentiment around PlayStation is at its most positive point of the month. Conversations around PlayStation are currently 85% positive, after dipping to 35% positive during the hacker PlayStation Network fiasco.

Wednesday we posted a sentiment comparison between Project Natal and the PS3 motion-tracking controller you can see here.
