So let me see if I've got this right, we're assuming sony has already won because its less ahead than it theoretically was last gen(remember, Teh Cell was almost 3 times as fast as Xenon!). Although, from a dev standpoint Sony's console is a mile behind, but its ok, they have some CUs that may or may not exist and may or may not render, and they will solve everything forever!
Also, despite having twice the RAM, Xbox whatever is gonna take up way more RAM with OS because thats exactly what happened last gen, when sony had 70+ MB of their RAM reserved for the OS, while Microsoft was smart enough to take a smaller fraction. Indeed, Sony is a pro at OS'es and will have a tiny 512MB reserved, even though the Wii U, with half the RAM has twice that much reserved, but Sony is awesome because they are an OS company and will manage to pack way more features than Nintendo in half as much RAM, and have a 7 times smaller OS than Microsoft, because what do those guys know about OS'es, right?
Clearly all the consumers, 99% of which have no clue what a CU or Flop or GDDR5 is are going to go with Sony because they will suddenly be enlightened because the PS4 will beam the knowledge of how much better it is on one or two specs than the Xbox because those two specs are the only real specs that matter and any specs that Xbox may have that are better don't really matter because they are not flops.
That about sum it up?
