These two are some of my favourites, the Monster Hunter one being the only special edition system I own. Also I've seen a few people posting Zelda 3DS's, but no one's posted the best one yet:
Yeah, that Zelda 3DS is the only limited edition console I own. It's a really nice shade of gold, not at all as gaudy as you might think.
It has convinced me to wait for limited edition consoles in future, particularly where Nintendo handhelds are concerned. They just love releasing a shit ton, and not only do they (sometimes) look great, they hold their value better too. I've not seen that Zelda 3DS cheaper anywhere since I bought it.
The good thing about the Switch is that I think Nintendo will release limited edition joy cons rather than the console itself, since there's more scope for interesting designs there. So just buy a couple of new joy cons and you have yourself a 'limited edition' Switch.
