Indeed. It is one thing being a consumer who can shift parts around a PC as they see fit, but to suddenly change hardware makeup involving supply chains, teams of people making games for your machine, financial budgets... not so much something you can react to.
That's a pretty damn risky strategy when they already have people developing on those dev kits.
I don't think for a minute that Sony's spec is based on anything but the rumours of what was in a Durango kit circa 2012. The difference is, Sony have announced now - the bed is made, they must lie in it. Microsoft will wait til around GDC, and announce then. We honestly don't have anything more than target specs and dev kits, and they could be playing a real game here and sold Sony a dummy.
That is what we're seeing here, IMO: Sony took a jump to react to the MS rumours, so it looks like they did it all first to the public. Microsoft let it happen, so they can react to that and change bits here and there, then commit it to manufacture.
And it's exactly what Sony just did, swapping 4GB for 8GB. You honestly think MS can't do the same?
We're working on old information for Durango. The first we heard of it was 28/2/12, for chrissakes. It's being kept very, very secret. The spec we're working on is from July of last year. Who knows what it is now? Early development kits are all we know. Period. I'm sure there's massive differences between the first and last dev kits for every console, and seeing as MS have now had Durango kits for TWO YEARS, I'd expect changes.
Seriously, we know so so little still. All Sony showed were promises. They didn't show a machine because it doesn't exist yet either. They even said themselves, "we'll let MS go first". All they've done is shown work in progress, expecting MS to have more than that and show its hand. Who knows what actually will happen, though?
