Also a good comparison is DSi that came out back in November of 2008. On it's opening week in Japan it sold 190,000. Next week dropped down to 110,000, then 90,000, and then back up to 114,000. Of course this is the DS so give or take some but obviously it was able to hold up well. Of course it did have the holiday season to rely on and a big release (Kirby Superstar Ultra).
It's hard to think we'll see a similar case considering PS3 is releasing in September, nothing on the size of Kirby, and no consistent software. But it's interesting to note it has the same explosiveness of the first week. Actually percentage wise it's going to be larger considering PS3 went from nothing essentially to 150,000. But we probably won't see the same magnitude of legs considering this is DS we are talking about. 150,000 to 80,000, to 50,000, to 35,000. Then of course we'd be looking at how it goes from there and where it stays at.
The point is in this time it's going to make up a fair amount of ground. In 4 weeks that's over 300,000 units pushed while Wii might do 80,000 to 100,000 in the same time frame. Nintendo need not be too worried but it needs something to give it some significant boosts as well. I'm not sure if Wii Fit Plus and New Super Mario Bros can do that. They are more there to make the holiday season flow.
