The Arkedo Series started life on the Xbox Live Indie Games channel, which allowed for rapid development, but not the large audience the games deserved. Now, it's being brought to PlayStation 3 by way of PSN.
Sanuk Games is sticking with "soon" as the release date here, but we have prices -- and they're looking good. Jump!, Swap!, and Pixel! will be a mere $2.49 each, and all three titles support Trophies. If absolutely nothing else, you ought to purchase Pixel! when it launches.
