GP100 is also available, but even fully enabled is the same shader count as the Titan XP but does have HMB2 memory.
So they could release a fully enabled 32SM count GP102, probably be a Titan Black, but that wouldn't be a 1080Ti (Though that is more or less what they did with the 780Ti, but that was to displace the AMD competition)
