This time around, it looks like the Playstation offering has better graphic chip and also faster memory, with what I was seeing is the CPU was comparible also. The PS4 is supposed to have more computing power. And add the price point being cheaper. I guess the recent bump in it is supposed to make it faster than the PS4, because they were comparible.
It is arguably the reverse of what you had with 360 and PS3, right down to price comparison.
It's actually worse than the 360 vs. PS3 situation. They had dramatic architecural differences. The PS4 and XB1 shipsets are similar. It should be far easier for developers actually show the differences between the platforms.
