It actually isn't overtracked.

The Dreamcast isn't the definition for worst selling console ever, anymore.

I don't think it ever was especially since the Saturn did worse :-/.

True. The poor Dreamcast just has such a bad name, quite undeserved too.

I didnt think dreamcast ever had a bad name did it? most people agree who had one it was a great console unlike saturn which was abit rubbish

That's very much a non sequitur. For Wii, Europe numbers were about 75% of North America numbers. For Gamecube, on the other hand, it was 35% of NA numbers. In between (chronologically) was the DS, which had Europe at over 90% of NA. Simply put, it's entirely possible for it to be doing better in one market, and worse in another. What's more, if we use Wii proportions as a guide, then Wii U is very much undertracked in Europe, since it's currently only at 51% of NA (and there's no official number releases for Europe except Nintendo's own, since the only people who directly track Europe don't release their numbers, even via leaks, most of the time).

That you're trying to assert "overtracked" by such a nonsense argument says quite a bit about you, though.

WiiU is overtracked and Dreamcast is undertracked (did 10.4m or something).

It seems m'y Predictions were too much optimistic for thé WiiU

meh its over tracked by 170k but hey
still possible to be undertracked in germany(wasnt it undertracked by 70k a while ago)

WiiU is selling rather well in South America, but many south americans bought their WiiU´s by importing from the U.S.A.

The question is.... does the NPD numbers include exported consoles or not? If don´t then WiiU is possibly undertracked in the region.
