Is this some pre-launch marketing for Google? I wonder if they're still able to meet their promise that they'll announce a 50-qubit quantum supremacy computer

Is this some pre-launch marketing for Google? I wonder if they're still able to meet their promise that they'll announce a 50-qubit quantum supremacy computer by 2017. Because the year is ending very soon. Was it delayed, or did IBM crash their party when they announced that even 56-qubits are not enough for quantum supremacy? (not sure if IBM's test was enough to prove that, though)
