If you look in the back, the Portal 2 cubes are there. This is more of an Easter Egg, considering the Portal 1 Companion Cube is technically used in-game, which means that at least somewhere, the Portal 1 cube must be used too. So the appearances of these are quite limited.
Portal 2's cube is better, in my opinion.

Why not a sphere?
It could have been, true. However, it is just a test chamber so I should probably keep cubes in-use.
I'd put the normally framed windows there instead, or use brush-based ones...
