Hi, 
 sorry Im not used to edit wikipedia sites. 
 I jsut wanted to say that the quote for the prediction that the BRIC countries will surpass the G7 in 2032 
 can be found in page 138 of: Goldman Sachs (2007), ‘BRICs and beyond’, Goldman Sachs Global Economics Group 
 http://www2.goldmansachs.com/ideas/brics/book/BRIC-Full.pdf 

 Cheers,
