It's mostly a marketing term right? They might do something like 0.5 or add some letters like X or whatever.

I think so. IBM recently produced a new "5nm" chip. In reality the physical size is closer to 24nm, if I remember correctly. The numbers you hear don't literally mean the physical size of the transistor, it refers to something else.

Most chips are 2D. IBM made a 2nn equivalent in 2D, by using 3D.
