But you are forgetting that most of those graphics cards use 1 or 2 GB, while the PS4 and the Nextbox (if the rumor is true) will use 8 GB.

Sure, they won't sell as many consoles as graphics cards, but each console sports 4x times as much RAM than a graphics card, so they will have an impact on the production of GDDR5 RAM, hopefully a good one.

Those Numbers also don't include FireGL or Tesla or Quadro or the various Notebooks that have GDDR5 Ram either, it's at-least double that number and maybe even triple if one is to be optimistic.

Sony would have also been stockpiling for months.
