Literally the very first bit of footage from the first reveal video showed that very feature. It must have been a really long series of insane coincidences that kept that knowledge from reaching you.
Keep in mind though, it's only compatible with certain games, though most do support it. And the range of the gamepad isn't very long, so expect to mostly play on your couch anyway.
