It doesn't matter what improvements are made in the next iPhone, there will always be some in the blogosphere that minimize the significance. It won't affect how many iPhones actually get sold to consumers, but there will be negative press. Websites get hits by bashing Apple, so they'll keep on doing it even if they have to make up junk.
The majority of upgrades to the iPhone have already been telegraphed in iOS 5 & iCloud. The A5 processor is a known quantity. The actual physical form of the phone is what most of the speculation is about. The punditry may scream bloody murder if the form factor stays mostly the same, but consumers won't care much.
We talked about disinformation or misdirection in some other thread. It's very likely Apple intentionally leaked inaccurate specs to case makers. First, it helps triangulate the source of internal leaks. Second, it keeps competitors (and consumers) confused as to what the next iPhone will look like.
