The Ion iCade, our favorite April Fools' joke turned actual product, has just passed through the FCC and moved one step closer to retail reality. The arcade cabinet for your iPad had all its Bluetoothy bits laid bare and even brought along its user manual, in case you're the type who bothers to read those sordid things. There aren't too many surprises here except, perhaps, the inclusion of an Ikea-esque hex key -- some assembly required. With the green light from the feds, though, that means the iCade is right on schedule for its May 31st release. If you want to ensure you nab one of the first batch, you can pre-order it now for $99 from either GameStop or ThinkGeek. And, while you wait for the blissful marriage of Atari's Greatest Hits and Bluetooth joystick, you can peep the pics in the gallery after the break.
