I am currently writing my diploma thesis to finish my studies and I am taking a look at the Blue Ocean Strategy and the video game market... What I am really looking for now are the production costs for the DS. There's plenty of information about the home consoles available but I cannot seem to find any information regarding the DS.
It's certain that Nintendo has not been selling the DS at a loss at any point but I need sources obviously so I can cite them...
So if anybody knows something... I would be grateful 
And please don't forget the source/link.
Edit: oh, and while you're at it: date for the psp would also come in handy :D)
