I wonder if HBM2 RAM might also be a reason for the delay. I've long suspected Nintendo would love HBM2 ... it has much lower power draw than GDDR5, and takes up much less die space, but provides massive bandwidth comparable to eDRAM (even the 3DS has a fast VRAM pool).
The downside -- HBM/HBM2 tech is very new and hasn't really been mass produced in large quantities yet, but it will be the RAM of the future no doubt. It was supposed to come in graphics cards this year, but a 2-3 month delay seems to be in order.
