My gut feeling for this is that this is the moment when a mockup is held up and the commentator says, "This is (Your choice of names here) and describes what it is/has in the way of shaders, etc. By is/has I mean will be/will have. Nvidia is late for doing this for the next generation. This would be what would, eventually, become the 1270/1280.
The 1180/1170, in a perfect world, will still debut next month and be based on a GV104 with the 1160/1150 to follow this fall and the 1180Ti to follow next spring.
