Bring 'rumored' availability option in the filter to the next level/rumor database?
I love the 'rumored' availability option! Maybe you should create a separate section of your site that deals with rumors - we all know how important they are, or at least important enough to slow the iPhone sales down..
In the separate section, you could gather all the rumors in the last month, for example, and analyze them - which came true and which didn't. Obviously you wouldn't know in just a month, but you can eventually build such a database that can tell you which sources are reliable and which aren't!
Hope you can think over that : )
