The 12GB of GDDR3 RAM just to claim more than PS4 to the average consumer makes it sound like absolute BS. Going to 12GB would require an entirely different memory controller and GDDR3 isn't even in production anymore, is it? Microsoft doesn't need to say they have more RAM, they'll just say they have 8GB and the average consumer won't know that the PS4 has an advantage there, if they even know the tech specs at all.
These pastebins are so obnoxious. Some people are posting them as jokes but several are posting them all seriously and saying they sound plausible. There's only been one legit one since the next gen rumors started and they're just getting more an more stupid.
