It depends on how far they're willing to go to use it. 8GB of HBM for unified memory should be plenty to last the generation. If they are going with a APU like AMD was saying then 8GB of HBM should be good. Maybe Nintendo keeps a little bit of DDR3 set aside to run the OS. 2GB of DDR3 should be enough to keep it functional.

8GB of HBM is not feasible today. AMD latest GPU (Fury X) will have "only" 4GB - 4GB of HBM would be amazing on an console. Also, when you're using HBM you need a strong GPU to pump it. In the end the machine would be pretty expensive. =/

But next year we'll have HBM2 already. Expect to see the Rx 400 and Pascall shipping with upwards of 12-16GB HBM by their 2016-2017 cycle. Not to mention GPUs have always been memory bandwidth starved, and remember how the X360 benefited of that 256 GB/s edRAM link. Of course the difference isn't going to be night and day from GDDR5 to HBM, but hey, it has lower power consumption and takes less space, so I think Nintendo might be interested by it.
