So it seems this Optimus Maximus thing is really coming out, I was still skeptical until fairly recently (I honestly found it hard to believe that those OLED displays in the keys were really going to work) but things seem to be going good.

The Optimus Maximus keyboard passed FCC regulations.

The keyboard is going to be shipping with a 512MB SD card to store the keyboard layouts so that the keyboard can quickly access them.

Also, here is what the box is going to look like for the keyboard.
