The new HB Bridges have two fins (to fit the two teeth on the 1080), unlike the older SLI bridge standard which only has one.  Therefore, the 1080 only supports up to 2-way SLI.
 
Based on the three lengths of HB Bridges, they can be used in three configurations (2-slot, 3-slot and 4-slot).
 

That's pretty dumb, considering Nvidia is essentially saying "please don't spend more money on our products!"  While it's true that 3-way SLI scaling isn't the best, this becomes decreasingly the case as you increase the resolution.  4K scaling for SLI is much better than 2K scaling for SLI.  Hence, 3-way SLI isn't totally stupid for 4K gaming, especially once we start seeing 4K displays above 60Hz.  While most people won't care about this, I see this as a step backwards.  What are enthusiasts supposed to populate their PCI-E slots with now?
 
Also, SLI support got a lot worse with Maxwell.  I partially blame the influx of new PC gamers, as PC gaming has grown a lot in the last 5 years.  The majority consumer type dictates the direction of the industry.  Since most consumers seem to think a GTX 970 is good enough for "maxing anything" and "smooth framerates," it's no wonder Nvidia stopped caring about the enthusiast who buys 2-4 graphics cards every year.  Unfortunately, I don't see SLI support getting any better with Pascal, given the trend.  My PC would look so empty with just one GPU 

A weird choice made that the new SLI HB bridge only work on the 1080...?

Not from a business stand point.  That is Nvidia saying "Buy a better card (read more expensive) than the 1070 if you want to use the double bandwidth bridge.  We are trying to help you make the right decision here."  You know it will be available on the Ti and Titan versions as well.

""Nvidia only supports SLI on 10 series cards""
The title suggests that Nvidia will no longer support SLi in older cards. (i.e. SLi no longer supported on 400, 500, 600, 700 and 900 series cards)..
 
I watched the entire video. And this is what he actually said ""They Only support natively, two cards.  You're welcome to do as many more as you want. But they are only supporting two cards in SLi for maximum performance.""

I 100% agree that this title is extremely misleading.

"Nvidia only supports SLI on 10 series cards" suggests the nvidia is completely dropping all SLI support for cards prior to the 1000 series.

"Nvidia will only officially support 2 way sli with the 1000 series cards" is FAR less click bait.

It's like what NVIDIA did with a previous slower model (I forgot if it was the GTX 950 or 960).
 
Because this route was taken, it could be because of three things:

• HB Bridge / motherboard limitation considering the high bandwidth travelling through it and/or strain on the motherboard respectively
• (if the first bullet isn't true) NVIDIA has a faster 10 Series to come out that supports more than 2-way SLI
• NVIDIA wants to limit your SLI decisions

 
 
Title should be like:  "Rumors - A Look at SLI with the 10 Series"
