Memory Sticks : 200$ for 2GB

Sony is planning to decrease the price of its 2GB Memory Sticks at the end of this month. It should now cost 200$ vs. 300$ today.
One can speculate that the launch of the PSP and Memory Sticks-compatible mobile phones might have been the basis for such a decision; but the release of the iPod nano might also played a role, since a 2GB iPod nano cost less than a 2GB Memory Sticks.
