Is this the first time a console has sold 2m in one week???

[thanny]

i was just wondering, has a console ever sold 2 million in one week like the DS just did? if so when was that? 

 seperate topic... its been 2 full years since the last brain training was released in Japan, it seems interesting there has been no word of a third, considering the second came only half a year or so after the first. wonder when the next will be?
