I don't think it's possible to eliminate the PLX switch since it's needed to for the GPUs to share the PCI-E bus.
It'd be nice to see sideport return if it can really improve CF performance, but we would have to at least wait until ATI's next-gen since it was cut from Cypress.

Correct. However, I think his idea was that the Sideport could be used to remove the need for the second GPU to be connected to the PCI-E bus altogether. I don't know if that's even feasible though, let alone beneficial. But it is an interesting idea.
