News from GamePolitics:

According to an anonymous spokesperson for the ELSPA, John Hillier’s quote about 90% of American DS gamers playing pirated software is completely wrong. In fact, the ELSPA doesn’t comment on anything outside of the UK. The article came from ‘The Sunday Post’ who got the information from a website in Singapore:

“The quotes from The Sunday Post were ascribed to his name from another article which originates from a website in Singapore. This, it appears, is where The Sunday Post first found out about the supposed R4 situation and for some reason unknown to John have quoted him on what this article said”

Article Here: 90%?! 

This explains things. Sorry Mr. Hillier.
