You managed to make the point better than I could. I wasn't born last night, and I'm fully capable of understanding a shift in naming. Benchmarks should sort this out. My prediction is that the 2070 and 2080 will occupy the slots vacated by the 1070 and 1080 respectively while the 2080Ti gets bumped up to the old Titan slot effectively skipping what would have been the xx80Ti spot, but again, this won't truly be sorted until we have more information on performance.
It's needlessly confusing, and I submit that it's also purposefully confusing. Using myself as an example, I always ignore the Titans simply because it's a halo product that is always overpriced compared to its xx80Ti little brother, yet I considered preordering a 2080Ti. In the end, I think this is going to backfire on Nvidia. They should have changed the naming entirely; the whole stack. Jay can insult his fans and Tom's can gush on about it all they want. It isn't going to change perception and precedent from 4 generations of branding. It's not just naming after all of this time. It's branding. It doesn't matter what slot it holds in the lineup, especially when Nvidia could have said as much, but chose not to. The 2080Ti, not the Titan T, not the 2090, not the 2080 Ultra, not the Nvidia Beastmode Ultra Uber Black, but the 2080ti costs $1200, and they did it deliberately, precisely because folks are going to allow them to get away with it by justifying a "naming shift."
