This ongoing specification discussion is kind of irrelivant for the most part isn't it?
For the most part, due to rising development costs, most games I would expect to be multiplatform, so whatever the weakest machine is, it'll likely hold back the other port of the game on the stronger machine (at least somewhat)
I recall all this shit 8 years ago re: 360 vs PS3 and it ended up the 360 had an easier to code CPU which was slightly slower and the PS3 had a bit faster CPU but ridiculously hard to code for. The GPU on the 360, I always read was a superior piece of hardware.
Before anyone freaks out - look at how it ended up? Best of the best 360 games looked pretty damn good, best of the best PS3 games looked pretty damn good.
I'm FAR more concerned with more significant things - what is the new controller design?
Can people swap in their own hard disks? I'm SICK of HDD performance - SSD or bust, I don't care how much it costs, I'm putting one in my PS3 in a week or so and I intend to put one in my PS4 if I get one.
What about features like remotely turning on? Remotely initiating downloading of games (like the Google play store for Android)
Will the device come with a second video output for no apparent reason (And end up powering illumiroom?)
How quiet is it, how much does it cost, does it still have optical audio out, will it support 3D or 4k (video, not games) does it have HDMI 1.4 or 1.3? etc etc
These things interest me far more than a CPU and GPU - as long as they are 'close enough'
