Its not actually something new, just a rearangement of components. Seeing as Sony used 2.5D stacking in the Vita its not that far fetched.
And I have to emphasize how much money could be saved, its Billions over years. And it ensures pricecuts for all consumers.
Smaller and less complex motherboard smaller power supply smaller boxes cheaper and less DDR3 modules.
Sony took out CPU GPU RAM in the PS3 within 12 months and changed the motherboard massively, they will take every possible way to cut production costs and the Ram is the most expensive part.
Sony will use it and probably planned that years ago. It makes no sense not to do it its probably part of the whole PS4 design philosophy from the start. GDDR5 seems like a temporary solution until 3D stacked Ram becomes a proven technology. Stacking Ram will replace all of Ram everywhere not just Graphicards but all devices, its the superior way to use ram. Its not a question of If but when Ram stacking becomes standard.
If they can make it cheap enough in time PS4 will have it and ofcourse everything else too. Not stacking Ram has no advantage (Unless your cooling sucks).
