There will be some new contenders, thats for sure. Soltek's KT133A mobo has the Auto-Overclock feature, fire it up and the bios automatically searches for the highest FSB speed. Getting 133 plus from regular 100 parts is a given.
EPOX 8KTA3 has been producing some impressive results. Personally, I'm waiting to see results of the Gigabyte 133A mobo. I believe that this is a first for Gigabyte in that it support OCing, both multiplier and FSB and voltage. The mobo includes Promise RAID and should be very competitive with MSI PRO2 Turbo.
