The armour thing was literally my first thought when I saw her reveal

They do redesign her based on the recent Zelda games though, because they want her style to match that of everyone else. For example, in the twilight princess art book they have TP style concept art of her for brawl. Interestingly though, we've now got: OoT ganon, a link to the past Zelda, Wind Waker Toon Link, BotW Link (and also a link to the past alternate skin), and... Smash Ultimate Sheik?
I just joke about the armour now, but it being gold doesn't really go with her default colour, or the red and white (the two most common skins in smash 4). Like if the armour was silver it could look pretty sick. The green skin is actually nice now though, partly because of the gold armour.
