You do realize the consoles have unified memory, meaning the GPU shares the same memory as the CPU. That Northwest Falcon PC you are talking about uses GDDR5 memory too, for the monsterous graphics card thats in it. So you have no idea what you are talking about.
It will help their sales if they launch a week earlier, but I don't think it will be significant to offset the PS4's sales, unless something has dramatically shifted in gamers heads that the xbox one is much better than original thought to be.
Anyone else feel like this is just one big stunt from MS, make their system seem terrible, then retract everything that is bad about it to boost its appeal. "Microsoft will not be revisiting the price of the xbox one"..... watch, it drops $100 by release.
