I'm currently watching a 100 watt multi-chip LED on eBay that's less than $30. Already have my DIY fixture built using 27 of the 10 watt multi-chips, but it's still a lot of wiring. If I could do 3 or 4 of these 100 watters, use optics & mount them higher..... it would be a pretty cost effective build with much less wiring. There's a thread on RC with multi chips where they are actually getting a manufacturer to custom design a multi-colour 100 watt chip for them. But I think that's going to be pricey at the start. Still be interesting to see where that goes.

Knowing how intense the 10w emitters are already, I can't imagine installing 100w emitters over my reef tank.

You don't have to run the 100 watters at full power and they are mounted quite high with optics compared to where I have my 10 watters without optics. With good quality optics & heatsink with fan, the 100 watt emitters mounted high are a good option if you like an open look above, with easy access to the tank. Manufacturers like Orphek & Kessil are leading the way with this form factor. Definitely an alternative to a multitude of 3 watt emitters mounted on large heatsinks without fans.
