Looks like Dungeons & Dragons 4th edition is coming; there's an GenCon event at 6:30 p.m., Aug. 167 in the Sagamore Ballroom. In the meantime, the Dungeons & Dragons home page is a countdown clock labeled "4Dventure". I was at the 3.0 announcement in 1999, and that makes me want to go to this event ... but not enough to blow off my Godlike event.
None of us are particularly surprised by this; rumors have been swirling about 4th edition for years, and it makes a certain amount of synergistic sense to announce the new edition of Dungeons & Dragons during GenCon's 40th year. It happens to coincide with our group's decision to take a hiatus from D&D for a while; it could be that when we return, there might be a new edition of the game waiting for us. Will we convert? I think that depends on how backwards compatible it is, and whether or or not there is an SRD available for it. Support resources, including the SRD and a good character creator, will play a critical role on deciding to upgrade to 4th edition; if there isn't a 4th edition equivalent of HeroForge I can't see us upgrading us anytime soon.
