Developers Sixense have announced that a bunch of new Portal content is coming to the PlayStation 3. It's called Portal 2 In Motion, and is DLC for the existing game that takes full advantage of Sony's PlayStation Move peripheral.
Crafted as DLC for the core game, P2IM was developed by Sixense, and brings 20 new levels to the game, along with new challenges and gear. Sixense will also be bringing Move support to the core Portal 2 game on PS3.
UPDATE - Looks like much, if not all of this content is the same PC users got hold of as part of Razer's exclusive Hydra DLC.
DISCUSSION
Well... on the one hand, you don't have to buy the Hydra game controller.
On the other hand, you bought the PS3 version of Portal 2.
