Yeah i cannot find anywhere selling the SLI HB Bridge yet, guess it might come out with the GTX 1070 release at a guess.
Like steaky says you can probibly use the one that came with your motherboard for the time being you just wont get the advantage of the increased bandwith.
Theres a SLI section here http://www.geforce.com/hardware/10series/geforce-gtx-1080 it has a bit to help you with Sizes. You have maybe seen this already though.
Hope this helps
Yeah I'll probably get away with the flexible bridge short term.
But I'm pretty sure I will need the 4 slot bridge when they become available, I will measure it properly when I fit the cards.
