Looks like Intel has some pretty big plans for major releases at the end of next month. Here is a ZDNet article talking about the new 820 chipset, support for 133mhz bus, and all kinds of other wacky stuff:

The 820 chip set will debut, along with two new Pentium III processors, a 533MHz Pentium III and a 600MHz Pentium III chip, on Sept. 27, sources said. The chips, which support the 133MHz bus, will be based on the current .25 micron Pentium III design.  Intel is planning to follow those Pentium IIIs quickly with the Oct. 25 launch of six new desktop Pentium III processors, based on its Coppermine technology.

Of the six new Coppermine-based desktop Pentium III chips, all are designed for use with the 820 chip set, and three, including a 500MHz, 550MHz and 600MHz, will be for use with a 100MHz bus, sources said. Three more, a 600MHz, a 650MHz and a 667MHz, will support either a 100MHz or 133MHz bus, sources said. Intel may release a 700MHz in place of the 667MHz, sources said, however this was unclear at press time.
