Now, this site wasn't founded on idle rumors of 3rd Edition, it was created after 3e was announced, as a place where what information we had could be shared and we could speculate and try and fill in the gaps from what we had, it wasn't a "I'll bet we'll have another edition one day" site.
Every week or so, somebody goes and posts a 4e rumor thread, which goes about like this:
1. Some "mysterious industry insider" said it's coming OR "Hasbro will make WotC do it soon."
2. People show up to ask for details about this mysterious insider, or to point out that Hasbro only cares about WotC's bottom line, and D&D is pretty under their overall radar.
3. People will also cite WotC's official statements about advance notice time, general satisfaction with 3.5e, and acknowledgement that 4e will happen one day, but no time in the forseeable future.
4. People will ignore that, and assume it will be out in a few months, typically at the end of the currently published product schedule.
5. People will point out that it violates WotC's statements and policies, as well as their obvious marketing technique of a Gen Con debut.
6. People will then say that anything official from WotC can't be trusted since they'll toe the company line and give propaganda, but their "mysterious industry insider" can be trusted (I always thought this was the funniest one, you can't trust their public statements they even give their reasons for, but an unnamed shadowy source is gospel truth).
7. There will be a separate sub-argument over the future of the OGL and 4e.
8. Tempers will have frayed by two or three pages into the thread, as both sides are deeply entrenched. Many people are sick & tired of new baseless (this poster, for example, is particularly fed up with people saying they have mysterious industry insider information that they cannot divulge the identity of their informant, but everything they say is true and if you disagree you're foolish. If you can't name a source in a debate so it can be verified, don't cite their information.)
