Ion Audio has introduced a couple new game controllers for your favorite iOS device, and — as you've probably guessed — CES 2012 is the place to check them out. The first, iCade Core (price TBA), is a desktop unit that is compatible with the iPad, iPhone, and iPod touch. Essentially a compact version of the original iCade cabinet, the device features a cradle that you can swivel from portrait to landscape mode, depending on the orientation of the game you happen to be playing. iCade Mobile ($99.99), on the other hand, is a handheld controller for iPhone and iPod touch that boasts a D-pad, four shoulder buttons, and four buttons on the face. Both should be available in the second quarter of this year.
