It really doesn't make sense to start with a platform that has hardware less capable than that of your competition and then price it higher.
Slightly faster CPU and Memory don't make much of a difference...just look at the PS3 vs Xbox 360...the PS3 had multiple core CPU etc etc and its games didn't look any better then the Xbox360. Just having bigger numbers when the specs are pretty close to one another isn't a "knockout blow" as some people are making it out to be. Its going to be the developers who are going to show if it is really that big of a difference or not.
PS4's GPU is ~50% more capable than XBox One's. That's not a trivial difference.
Whether the difference will matter
in practice is a different question. It's possible, for example, that most cross-platform games will be developed with the lowest common factor in mind. It's also possible, and probably more likely, that because the two new consoles use nearly identical architecture, that every game will simply look better on PS4. (Xbox one gets normal quality settings; PS4 gets "console Ultra").
