Therein lies the caveat: "games that scales on CFX/SLI". You're banking on the hope that CFX/SLI works, when it doesnt you're back with 1 card and worse still, you card is midrange. That is why one single powerful > two midrange. There is still that problem with framepacing that remains. ""It's not about how fast you go, it's how well you go fast!" You can go fast by adding two engines instead of one, but if the ride is bumpy as hell, you're not gonna enjoy it compared to a more powerful single engine.

I agree. SLI/ CFX is entirely a hit and miss thing. At the end, it all boils down to what games you play. I'm just looking at this from a viewpoint of person on budget who can only afford to fork out for RX 480 or the upcoming GTX 1060, and maybe able to save a bit within 6 months to a year for an upgrade. Since GTX 1060 not going to have SLI, I'll take RX 48- as example.


Two games that RX 480 CFX performs decently, on par with GTX 1080 and OCed GTX 1070


Two games that might as well take the second RX 480 and burn it coz its totally useless.
So if that person plays the 2 games that do well in CFX, well they have an option to get another RX 480 to crossfire, or they can sell the RX 480 and get a better single GPU. If they play the 2 games that's crap at CFX, well only option to upgrade is sell it off and get a better single card. Its about options.
In the case of GTX 1060, I firmly believe that performance will be better than GTX 970, and maybe even be on par with GTX 980. And if it had SLI capability, I believe it would do even better than RX 480 CFX. But well, that option is not going to be available, because it will jeopardize GTX 1070 and 1080 sales. Profit Margin 1 - 0 Budget Consumer.
And same thing with the frame-pacing issues. Its the managing tolerance between increase fps with SLI vs frame-pacing issue. If frame pacing problem is inherent and is so bad in all games that runs SLI, I think nvidia would also forgo the SLI for GTX 1070 and GTX 1080. But some games already showed a marked improvement in frame-pacing with the new Pascal arch.

Maxwell SLI's earth quake.
Pascal GTX1070 SLI.
I believe Nvidia will continue to improve their SLI implementation so that the benefit of increase fps (both avg and min) far outweighs the frame-pace issues. I heard rumors that GTX 1080 Titan will be 50% faster than GTX 1080. Based on current SLI benchmarks, I'll probably get another GTX 1080 to SLI, rather than sell my current GTX 1080 for a single GTX 1080 Titan.
