I now DO NOT think the seats submarine forward. After thinking through it some more, the pedestal design, as depicted in the interior rendering, just doesn't support that movement very well. It would not clear up much floor space to have that large pedestal behind the seat. The pedestal design does support an outward rotation however. I think the gap at the front of the pedestal (as seen in this processed pic:

So if anyone's keeping track or cares, my prediction is:
3rd Row:
- both seats fold aft like in a minivan
- this creates a level loading floor from the hatch opening to the shelf above the motor
2nd Row:
- the 3 seats operate independently
- the pedestals translate in the floor fore and aft
- the seats recline as a unit (the lower portion rotates up with the backrest)
- the outboard seats rotate outboard to assist with kid or infirm people ingress/egress
- to get easy access to the 3rd row, the outboard seats translate forward
- to maximize cargo volume, all the seats translate to the forward extent of the pedestal travel
Enough for now, exciting times ahead for those that have been ever-so-patently waiting for the production configuration details.
