The 600% increase number (actually, it was 666%) was in the UK, where sales data gets collected and released within just days of the end of the week. In the US, Nintendo generally waits for NPD data before releasing PR info regarding hardware sales. To demonstrate, here's the NoA press release just after MK8 release:

Still waiting on my friend to get smash bros. I told him that i bought it and he has two days to get it until it arrives a my door step. Lets see if he gets it xP If he does ill go to the store and pick it up, shhhhh ;)

That is true. My bad.lol

It still has 13 million vs 3 million WiiUs though:)

3DS has an install base of 14.4m in the US while the Wii U has 3.2m, over 4x the amount. 490k for Smash Bros. for Wii U is a pretty good figure, considering those circumstances.

Especially when you consider that that constitutes somewhere in the vicinity of one in six Wii U owners (assuming no huge bump in hardware sales) bought the game in the first two days.

Even worse than that! 14.4mill vs 3.28mill. So 500K in 2 days of sales is quite impressive,lol.

Yes, i just wanted to correct your stamement. No offense or shouting out your hint is wrong ;)

3 days

"with more than 490,000 physical and digital units combined sold during the three-day period of Nov. 21 through Nov. 23."

fingers crossed WiiU will be over 100k this week

Don't get me wrong, technically yes 500k in two days is amazing for a game in one territory, but this is suppose to be Nintendo's biggest game of their generation (that we know of).  So maybe with all the hype that's been going around made it seem like almost every NA Wii U owner (except for me) was going to pick it up , so 500k didn't seem as much as I was expecting.
