The key here is that Dev kits have more memory but they don't have a different chipset and certainly don't have a different graphics card.
Battlefield was shown using a PC that much we know.
What we don't know (and probably wont until launch) is how much quality difference there is between what has been shown and what is available....
*BUT* with sites like Eurogamer and people on the internet, they will soon find out the differences. I get the impression that the PS4 is more powerful than the XboxOne, I am getting the PS4, so I am not too concerned about it... but if people are, i would wait until after release and some game comparisons come out, it wouldn't be long after.
