That's the best picture I found in the web comparing the size of the two new next-gen consoles.

What do you think?
UPDATED: Volume comparision by @binary solo... thx
Estimated volumes (i.e. how much space they take up)
Xbone: 7216 cm^3 (So close to being 720...times 10)
PS4: 4445 cm^3 (look at all those 4s!)
PS3 phat: 9236 cm^3 (phat by name, phat by nature)
Xbox 360 phat: 6616 cm^3 (ooooh 3 6s the number of the Beast)
Volume-wise Xbone is 62% larger than PS4. PS4 is less than half the size of PS3 phat.
Xbone is 9% larger than Xbox360.
