OCZ introduced a new product today, bringing their first triple-channel memory kits to the market. They are calling it a "world's first," and pitching the new memory to the as of yet unreleased Intel X58 Express platform that will make use of Intel's Core i7 processors.
The first triple-channel kits will be available in 3GB and 6GB sizes, with either 1GB or 2GB per channel. The modules are designed to be low-voltage, necessary for CPU compatibility, requiring only 1.65V regardless of what speed module is used. They are available in PC3-10666 and PC3-12800 speeds, and will initially be available in their Platinum and Gold series, which are typically aimed at enthusiasts.
OCZ's hardware is ready, but the platform it is aimed at is not, so I doubt they'll be selling many of these right away.
