While details are scant, there's good reason to play close attention to the game. Just Add Water plans on charging as little as $1 for the game on the Minis service, introducing pricing parity between the App Store and the PlayStation Store for the first time. For PSP owners frustrated at overpriced Minis, Vektar Beat represents an interesting experiment.
Vektar Beat is scheduled for release in the Spring. Further details are scant for now, but tonight's episode of the PS Nation podcast should reveal much more.
