No, he said he's not getting dragged into a pissing match over specs.
If I give voice to my inner cynic, this could be a cunning PR campaign. We know MS needs to actually manufacture these things ahead of the release date, so the time for changing specs is measured in weeks, and you can't change much in a matter of weeks. However, suggesting you can, and throwing the question to the public, you get the public coming up with explanations as to how the "weaker spec" console can be the better performer, effectively creating FUD. MS would then just have to say, "no comment," and the fanboys will run wild with unsubstantiated speculation, evangelising how much better XB1 is without actually knowing that to be the case because the theories are based on guesswork and wishful thinking.
eg. Penello : Can anyone come up with an explanation about how our hardware could perform faster than PS4 given the specs we know?
Gaf 1 : What if the ESRAM provides far greater ALU utilisation.
Penello : Indeed, what if?
Gaf 2 : What if the custom blocks, the depth and colour and memory move blocks, are much improved?
Penello : Yes, what if?
Rest of the world for the next few years : "Even if PS4 has more CUs, XB1 has better efficiency and improved custom blocks. It's a far more efficient design. Penello pretty much said as much."
Of course, in that example Penello says nothing. the smiley faces are used to imply the affirmative, but they have zero real substance and none of those theories are substantiated. But it equips the MS fanbase with some arguments that the fanboys will press relentlessly for the rest of the generation. We see it time and time again, idiot fanboys believing and evangelising and talking shit, and from a business POV it's probably better to encourage that than lay the facts out straight and eliminate the confusion. FUD = Fear, Uncertainty, Doubt. If you're not in the strongest position in a particular field of your market, uncertainty and doubt help obfuscate your opponent's advantage.
I'm not saying that is what's happening in, but I hope people bare that in mind regards everything they ever read from a Sony or MS mouthpiece. The only meaningful information is that which comes from engineers are hard numbers and facts. Everything else cannot be corroborated or evaluated, and shouldn't be given any weight - for any platform and for any rumour. We know PS4 has 18 CUs because that was a cold, hard fact from Sony. We know XB1's GPU can execute 768 ops per clock, pointing to the leaked 12 CU spec, as that was a cold, hard fact. All the non-facts are wielded for marketing purposes, and not to inform the buying public.
