Sony sent out a bunch of trailers for first-party launch Vita games, focusing on the Vita-specific features each game uses. The good news: we see clever combinations of controls here, like Escape Plan's "pinch" of both the front and back touch panels. And Gravity Rush looks really neat regardless of how it's controlled.
The bad news: we're not nearly mature enough to see ten references to "front touch" and "rear touch" without giggling. If that's how Sony is going to refer to those features permanently, we're going to have a problem at press events.
