You can kind of see what might have happened though, 2004 seems to be their worst year, after which the DS saved them.... had they not released the DS (instead waiting and releasing a new GB in 2005/6 followed by a non-Wii) what might have come to pass.
Although to be honest Nintendo could probably run ok on 1st-party franchises.
I assume that the 2008 number is still incomplete... which means 2008 might see close to $3billion in profit. Immense numbers.
In fact in those 3 quarters of 2008 Nintendo has made more money than the entire PS division.
