I just saw this myself! Interesting tid-bit:
Each of the eight black squares on the board is a chip capable of computing 7.5 GH/s.
The Bitforce SC Jalapeno will use a modified board with only one chip, whose operating capacity is further reduced to meet the limited power availability through the USB bus.
So the jalapeno will be the same size, but will only have one chip, and it's going to be downclocked at that. Also no need for a heatsink/fan with only 5W, but that fact has already been established.
Prediction/speculation: I'm assuming that that means the Little Single only has 4 chips, and the SC MR will have all 8 chips per board, but will run at higher clock speeds, but also be WC'd.
