Sony announces 2GB Memory Stick Pro Duo for less than $200 going on sale end of September.
Until now Sony only had the 2GB High Speed Memory Stick Pro Duo available, which sells for $346.99 on Amazon.com.
The new 2GB Media Memory Stick Pro Duo lists for $199.99 on SonyStyle for pre-order. I would think that other stores will have lower prices soon. More details in this Sony press-release.
