Well, that was done with the 128-qubit version, right? And now they have one that is 2^384 faster than that one, so we'll see what happens next.

If it was the 512-qubit one, then we'll need to wait for the 2048-qubit D-Wave Three that should come out in 2015 (they seem to double the qubits every year, but only release a new model every 2 years or so). That one should be 2^1536 faster than the current model.
