That way the PCB is a lot less complicated (=cheaper) and we do not have to duplicate VRAM and deal with scaling issues.
Whit this logic, you are dismissing the idea of double-GPU too.

Big and powerful single-GPUs is great, and the best option for most gamers, not everybody tho. But Double/multi-GPU has many advantages for HPC/GPGPU setup, where you can have many more, due to limitation of the number of PCIe-lanes.

I personalty believe we are going to see 3 (or even 4 ) multi-GPU soon, maybe not exactly in this round, but in near future.
