Can someone explain the Fuji mirrorless lineup?

I only know Sony's mirrorless lineup in ascending order, it goes something like:

NEX 3 series > NEX 5 series > a5000 > NEX 6 > a6000 > a7 (the NEX series will probably be phased out soon)

I'm not sure how the Fuji APS-C lineup is like, though, so an explanation as well as a comparison to Sony's lineup would be great!

(My current guess based on prices is: X-A1 > X-M1 > X-E2 (a lot of missing models here))
