Well I don't really care either way but if a review site showed you pictures of an item and told you it would be available somewhere, someday with no specifics other than the fact that they have on and you don't you would get similar response.
Well, I don't know what you expect here. Poster got their hands on a case that WILL be released by Nokia, but was asked by the person who provided it NOT to disclose how they got it. It's clearly from some kind of inside source, and they are respecting their wishes.
Review sites can sometimes get devices and products to review months before it is released to the general public. The purpose of letting the public know through pictures, videos, etc is to inform viewers what is coming, its experience, etc. That's all this poster did. Here are DETAILED pics of a case that will be coming out shortly (this month actually). And hey, it's just a case for crying out loud!
And like I said, I have the feather case in the interim and I didn't shop around at all because of the detailed pic offered by this poster. For that I am thankful, not unhappy that they have access to a case before I do. I now know what I want and will wait for its released to update my case. That's all my friend.
