The new 2021 X2 Mesh Edition also features Brooklyn Grey. The press shots were taken at sunset so it's kind of hard to judge the true color, but it seems very close to a lighter Nardo.

I'm kind of torn now. I currently have a Nardo F80, and was planning on ordering a Nardo G80. I don't like BG as much as Nardo, but it does seem very close and would save me ~5K.
