Some random notes:
RAM manufacturers are already phasing out DDR production. Just as with SDRAM, DDR is going to become an expensive old technology. DDR2 is ramping in fast ( and DDR4 is following soon ).
PCI-E is the same, it doesnt matter if the technology makes a difference to the end user, for the people building the boards it is worthwhile, and moving into the market fast. not supporting it in new products is going to be suicide.
AGP 8x does support two slots, but no one ever made a chipset or a board that used it - because there were very few users who needed high speed 3d on 4 displays, and no one making SLI cards. I think it is being used by ATI, their IGP built in video will continue to work if you plug in an ATI AGP card, giving you 3 video outs.
If you have a look at card manufacturers, there are already plenty of nvidia 6200s coming onto the market ( PCI-E ) with only 16mb of vram. They host all of the textures in main system RAM ( upto 256mb ). Im sure that they dont perform very well, but what do users know, its a cheap card that can do everything.
PCI-E, like hypertransport, provides a fast way to connect to devices that is standardised. However, it is also flexible. Only want to give a device a 1x connection ( because of board space, or availble channels, or pins on the chip etc etc ) and you can. You can take a 16x video card, and mask off all of the pins except the 1x, and it will still run. That is just great technology for board designers.
