Will iPhone 5s gold retain its value couple years later?

I wanted to get the Grey 5s but I can tell that gold is getting enormously popular. Considering that I will be selling my 5s couple years later when I upgrade my phone again, should I get the gold even tho I like grey more than gold? Do you think gold 5s will lose its popularity by then?

Not any more or less then the other iPhones.

Nope. It will be worth even less than the black or white ones.
not many ppl want the gold one

Iphones retain their value really well, even iphone 4 costs alot if in good condition.
