And just common sense. Moments after I got into that leak thread I was calling ntkrnl out. These are orchestrated leaks.
Even if you're just looking at the quality of information you can see a pattern in how many projects are referenced/revealed without there being any real detail. It's a desperate move, yes, but I could see someone at MS, in their desperation, approving the names of these titles being revealed, knowing it would ripple across the enthusiast crowd and distract from their situation without totally ruining official reveals in advance.
Think about it, we all know Uncharted 4 is coming. Officially. But we have seen absolutely nothing of it. And we at no nothing about it other than the cryptic monologue from the teaser trailer. But the hype is real and palpable.
MS knows they can afford this. Tease all these projects in the pipeline to get enthusiasts to hold out on buying a PS4 or at least to feel confident buying a one. It's a risky, subversive move, but I think--judging by many people's reactions in that original thread--it's working. :/
