My apologies in advance for the huge image, but there's some interesting details in there.

You can pretty clearly pick out which one is the prototype we've been seeing so far and which are the two new ones, also, it looks like they've got quite the collection of whimsical prints on that cart from their stress testing. The big green cylinder looks like it might have taken up most of the printer's build volume, and from what I can tell might have been used to test out different methods of infill.

Still looking good, there.
