The uber edition I think is just speculation. There was a forum post from BioWare entertaining the idea of a edition for the hardest of hard core collectors:

The comparison was to MW2 prestige edition... pointing out the cool functional night vision goggles. That leads me to think that the 'uber' part of the name is for the price and not necessarily the quantity available.
