Looks like cylindrical cells
Arranged in bricks, then ganged up in sets of two bricks. 4 holes... maybe two for liquid thermal management and 2 for electrical hookup.
It does appear that the design does not preclude hot swap someday.
Interesting that the shown rendering doesn't extend the battery pack up into the front of the chassis. The Model S skateboard has two more modules in front:
Since the Model S is pretty big already, volumetrically that reduces the amount of batteries you can hold dramatically.
