Sony teasing new Vita game with empty boxes

Like some corporate nightmare (or pleasant dream if you like the post-room) two execs wake up to find themselves surrounded by cardboard boxes with "open me" stamped on them. In the last one they find two Vitas, suggesting multiplayer, but on the screen are just more boxes.

What could it all mean? Snake likes hiding in boxes, but this isn't a Konami trailer. Sony Japan will probably let us know more at Tokyo Game Show. Any thoughts? I'm thinking something by the EchoChrome guys, but only on the merest hint of a synapse firing, but this seems a lot effort for that kind of game.

There is now a site for this, which doesn't give much away, except that it is a download only title.
