Sony has taken legal action against companies and sellers in China and Taiwan that are selling fake memory sticks with the Sony mark on them. eBay sellers have been making a fortune ever since the launch of the PSP through selling fake Memory Stick Pro Duo's through the online auction site for half price, making out that they are genuine Sony/Sandisk memory sticks. In April we wrote an article on the difference between the Real and Fake memory sticks, as well as a report on the quality of memory sticks sold on eBay.
With Sony suing companies, its pretty obvious that most of the memory sticks on eBay will disappear, or will be re-branded with something else. The thing is, most people that buy the fake sticks know they are fake. All the sellers have to do is add another brand on them, and I'm sure they would still sell in the thousands. I know that for the price I bought my fake stick for, I'd still buy it with another label on. Make way for the Sonny Memory Stick Pro Duo!
