It wasn't DS, it was Nintendo DS, people knew it was a Nintendo console, NX is too vague. If they called it Nintendo X it could be confused for X box, if they called it Nintendo Cross there are people in the US anyways who might mistake it for a religious thing, see some of the talk back threads. DS stood for Dual Screen, they made that clear when they were talking about it before hand, so far we know literally nothing about "NX" so what does it supposedly stand for? It is terrible in that regards. It sounds cool and people have gotten used to it but Revolution sounded a thousand times infinity better than that idiotic, piece of ****, no good, nothing, stupid ass, lame, crap fest name they went with.
DS didn't sell one console because the name, not calling it Game Boy had no impact either DS was like the Nintendo Piss, it was right place, right time, but the damn was lame.
