In case this is your first visit to Joystiq, know that Sony has dropped major megatons this evening at its GDC press conference -- as well as one very small megaton: the PlayStation Move "sub-controller." What you see above is the little brother (if you will) to the main ice cream cone–esque Move wand and the enabler of all things analog stick-controlled.
As per Sony's announcement of Move, the sub-controller attachment is intended to "expand the game play options that PlayStation Move games can offer," and -- unlike Nintendo Wii's Nunchuk controller -- it will connect wirelessly to the console via Bluetooth. We'll have our hands-on with the PlayStation Move (and the sub-controller) for you later tonight. For now, ogle the high-res images in our gallery below.
