Thats for a PC though. I imagine allowing Hybrid crossfire on a console, with a static system to develop for could be pretty good.
The only way I can see dual graphics going down is APU iGPU used for dashboard/media in low power state with a dGPU for gaming + Open CL for various compute on the iGPU
AFR sucks really hard unless you have identical hardware (APUs are let down by slow/narrow memory interface)
Interesting to see what the come up with in any case though
