Over on the D&D site there's a countdown for a 4dventure that has the internet up in storm. Is this the long rumored, conspired D&D 4.0? It's it a countdown to a new setting? Or just someone at Wizards joking with us?

Well it is gencon week so if something was going to be announced it would be now, but I don't think it's a new version. For one it's "adventure" with a '4' instead of an 'A' so I'm thinking it's a new setting since there are 3 official settings right now (Greyhawk, Realms, Eberron) but I could be wrong. Another valid option would be for the online versions of Dragon/Dungeon--the name escapes me at the moment.

Why I don't think it's 4.0 is I don't think people would buy it, 3.0-3.5 was tolerable because the two were still similar enough to convert and 4.0 would imply something that's not compatible with the 3.x line. We'll know in 5 hours though.
