I think part of it is that, sure, leaked iPhone spec's will always get some attention, but it's nowhere near as big a deal as the first few iPhones or other new product launches. News of the next minor evolution of iPhone spec's probably aren't profitable enough to devote resources to fretting them out. I think we're past the point where (for established products) it's as big a deal as when Gizmodo got a hold of a pre release.
