it's not like the crap that are CNR and AMR slots. I'm prolly sure it will remplace the AGP, as the PCI remplaced the ISA and the AGP the PCI video cards. CNR and AMRs were "added" things , started by IBM, not remplacement of other ones. Rambus was "another" type of ram , it wasn't remplacing other ram types and actually, only INTEL used it. For the PCI-E , since every companies are using it , form both chipset and video cards sides, it won't go away. and also, the PCI-E is MUCH MORE performant and doesn't really cost a lot more. why remove smth that is way faster? (for the RIMM, it was too expensive so, that's mainly why)
