Sony Memory Stick PRO Duo Goes Up To 4GB

This one doesn't quite go up to 11, but PSP owners will be happy that their maximum storage space has been doubled from 2GB to 4GB. That's a lot of homebrew apps and movies you can be storing. The MSX-M4GS will be available in Japan during August, so if you're interested you should find a Japanese store now.

The price of the 4GB should be more than twice the cost of the 2GB memory sticks, which is around $119 now.
