they're not 3 and 4 way bridges. They're for different slot spacing of two cards.
Oh balls!!!!
Those are all 2-way SLI bridges. The reason the sizes differ is to accommodate different PCIe spacing. NV ran the VR Works demo with a custom 3-Way bridge but the 3rd 1080 was only a dedicated PhysX card.

Since 2 SLI fingers are required for 2GB/sec, you cannot have HB beyond 2 cards, essentially eliminating the feature.
So maybe you can still have 3 and 4 way but it will just be gimped. That's fine I guess.
