There's no guarantee Apple will actually turn it into a real product, but we hope they do -- mostly for the sheer entertainment value of poking whatever spongy substance looks to be forming the base of the dock.
That magical substance -- we imagine it like some sort of cross between Play-Doh, Sticky Tack and prosthetic skin -- would conform to the shape of whatever Apple mobile device you throw at it (iPod nano, touch, iPhone, etc.) to provide a power charge without requiring one specific preordained form factor. The dock would then be able to keep an imprint of the last device used or be reset to accept a different device.
