PCI Express, will that type of bus eventually replace PCI as well with say 6 or 7 connectors on the motherboard much like PCI replaced ISA?? Can it be used for more than just video, say SCSI controllers etc?

there are 2 types of slots under the PCI-Express standard, PCI-Express x1, and PCI-Express x16. The x16 slot that you hear about the most is the replacement for AGP, and the x1 slot is the replacement for PCI. So yes PCI-Express can be used for things like SCSI controllers

Actually, there are 7 types of PCI-Express slots, x1, x2, x4, x8, x12, x16 and x32. The ones being used most are x1, (from what I read backwards compatible with todays PCI cards), x2, x8, x16.

If anyone is interested, here is a white paper link explaining the operation of PCI-Express.

Give that a read, it should clear up a lot of misconceptions concerning the newest system bus to enter the market.
