Olympus has announced 1GB XD card, and Sandisk announced 1GB MiniSD card too. I could have that for my MPx 220

"The 1GB miniSD card provides a level of storage that significantly enhances the features and usability of these full-featured mobile phones," said Nelson Chan, executive vice president and general manager of SanDisk’s consumer and handset business. "For example, with a 1GB card you can store approximately 16 hours of MP3 songs, record up to several hours of MPEG-4 video or take more than 2000 digital photos on a 1-megapixel mobile phone. With that level of capability, consolidating music, video, digital camera and other key features into the mobile phone platform is much more meaningful and powerful."

The SanDisk miniSD card includes an adapter allowing it to be used in any of the existing SD card devices. The new 1GB SanDisk miniSD card is expected to be available at the suggested retail price of $99.99 in Q2 2005.

SanDisk also announced was the 512MB SanDisk TransFlash, one of the smallest flash memory storage cards designed primarily for the mobile phone market.
