Yeah, and the triangle and the half-hidden neon colours binds it together with AND Tour and also W FACE Tour (which already had a 80's theme, though in another direction).
If you look at the concepts of the albums and tours you can see that Kuu and her team pretty much see the years 2017 and 2018 as one big cycle.
Though I also think it's a pity that the "looking back in the past, but also forward into the future"-mix of the DNA album and tour is not really visible in the covers.
That Kuu and her team are usually planning way ahead is really visible in stuff like that.
And we know from her FC blog, that she and her team already roughly planned new starting now till 2021.
Idk if you guys noticed, but the tours being 80's themed for two double albums, which are dealing with Kuu and her development and her identity, can't be a coincidence - she was born in the early 80's after all.
