1. There really wasn't an 880...sure, there was an 880m, but, no one really cares. 2. Nvidia has changed their naming before. Examples: x80 and x080 have been the current high-end pieces, right? but what about the 9800 GTX? 8800 GTX? 7900 GTX? And if we're going off of naming, then the one below the x080 or x80 has always been the x070 or x70 right? But then what about the 8800 GTS? 8800 GT? 7950 GT? 9800 GT? Oh lets just throw some other outliers out there: 6800 Ultra, 6800 GT, 6800 GS, 6800 GTO, 6800, 6800 XT, 6800 LE, PCX 5950, GeForce FX 5900 ZT, GeForce4 Ti4600, GeForce3 Ti500, GeForce2 Ultra, GeForce2 Ti, GeForce2 MX400, GTX 285, etc etc etc etc. The list can go on and on. So don't pretend to say that nvidia has a specific naming, they can, and will change it whenever they so please. Technically, the 1080 was part of a new naming scheme potentially, just like when they went from 9800 GTX, to 280.
