Patapon-related beta test teased

As tends to happen around this time of year, another countdown site has popped up, this one on the Japanese PlayStation site. It's counting down to the start of a beta test for ... something, with the countdown against a black background, with some thunder noises for ambiance.

Well, not just for ambience. The thunder accompanies a faint lightning effect, which illuminates a faint Patapon-esque scene in the background (above). But why would a new Patapon game need a beta test? What if it featured (gasp) online multiplayer? You'd be all pata pata and your friend would be like pon pon and it would be awesome. We'll find out in around five days!
