There was a 10 year gap between Daggerfall and Oblivion. In the 10+ years since Skyrim, we've gotten a trailer.

The last time I was really wowed by a trailer for technical reasons was in 2015. I saw the trailer for Metal Gear Solid 5, and thought "Ah, that would justify a new generation then." I have not felt the same way again ever since.

This game came outthe same year as Duke Nukem 3D and Quake, btw.
Although, tbf, Daggerfall is a wrpg so it's sheer size already meant that graphics wouldn't be able to hold a candle to what those inhumane geniuses of Carmack and Silverman were into.
