At first thought, you'd think physics (2x16 cards + mis-matched card at 8x for physics), but AFAIK every card out there currently can use 8x, where-as the 680i could then handle three...hmm...I wonder if it's both for physics and 3x (or up to 6x with GX2-type products) SLI when physics isn't in use. Physics is probably true, 3-slot SLI prolly not.
Regardless, I'm sticking with the one good GPU for processing + one lower-end end card for physics (when that's supported by nvidia/ATi-AMD), so I couldn't really care less if they do 3-slot SLI. Good to hear the mis-matched cards for physics will finally see the light of day from both Nvidia/ATi though, it's been a long time coming...Maybe we'll actually see games utilize them (unlike physX)
Unless PCIe 2.0 specifications will allow to make Motherboard 4 of um PCIe slots @16X speed. So you can have Quad physical PCIe cards Nvida G8x series GPU's.
What VR Zone and Dailytech are pointing at seemed like pretty weak beer to me so far as earning so grand a moniker as "SLI 2.0". But maybe, I guess. The ways of Marketing departments are mysterious at times.

Um, as far as I know there is no limitation on how many PCIe slots you can have on a motherboard by the PCIe spec. It's purely a chipset issue. PCIe 2.0 will bring higher frequencies to the table.

Not too many people thought adding some SIMD instructions warranted an increment of the moniker to Pentium III. And I didn't feel like nForce4 was as big an advancement over nForce 3 as 3 was over 2 (or 2 was over 1). But new names spur new interest.
