At this point, if they announce anything different, the greatest fans of the Dragonlance setting are going to be pissed and out for blood. You just don't invite people to a show where you are going to announce the new D&D setting and turn around and kick them in the Jimmy.
Well if it is, it will be the first 4e setting I'll buy. It isn't my first choice (Al'Qadim, oh how I miss thee), but Dragonlance has always had a special place in my heart.
The Old Republic era is something more like 150 generations before the Dark Times/Rebellion era. There's a difference between the "Republic era" that exists during the time of the prequel films, before Palpatine becomes Emperor, and the "Old Republic era" of the Knights of the Old Republic comics and CRPGs and the Star Wars: The Old Republic MMO that's coming up in 2010 or 2011.Or compare that to Star Wars, with the Old Republic in one generation, the Rebellion Era in another, and the New Republic/New Jedi Order in a third. 130 years after that is the Legacy Era. Sounds like they have galaxy-shattering events every generation.![]()
I'd be surprised if Dragonlance works in the context of Fourth Edition's de-emphasised alignments, non-Good metallic dragons, et cetera.
Hmm... I'm thinking that I'll probably keep getting Player's Guides as long as I'm gainfully employed or otherwise not broke (and WotC keeps up with the Player's Guide/Campaign Guide setup for settings), but assuming Dragonlance is the next setting, I think Eberron is going to stay the only Campaign Guide I pick up for a while.
WotC will make it work one way or the other.
Thats why I am not too thrilled if WotC decides to 4Eize Dragonlance. The results will likely be worse than what they did to FR.
Dragonlance, Dark Sun, Greyhawk and Ravenloft were all popular in their day, and all have vocal followings, so the anniversary clue would be key. 2010 is the 25th Anniversary of the Dragonlance novels, and the 20th anniversary of the Ravenloft campaign setting. Dark Sun, meanwhile, celebrates its 20th Anniversary in 2011.
If they want to leverage anniversaries, I'd say it'll be DL in 2010, and DS in 2011.
