mxyzplk said:In 4e, Wizards is clearly saying that anyone expecting Greyhawk, FR, or Eberron to continue as before can go hose. And supplements, scenarios, etc. from previous editions will be totally unusable. And, frankly, anyone who has a specific character type they liked in previous editions has a good chance of not being able to recreate them.
Published material can continue in any way you see fit. My campaign is set in the original grey-box FR setting, converted to 3E, and works perfectly. Personally I can't stand the 3E re-make of FR so I don't use it, and probably won't use 4E FR either - though it's more likely I will take the concepts I like and incorporate them.
Those previous supplements will be just as usable as the 1E and 2E ones are now, ie, really fun to shoe-horn into your own campaign, in the way that you like. Anybody that took an old classic like one of the Giants modules knows I'm talking about

As for previous characters, the devs mentioned that _converting_ them will probably not be possible, but recreating them obviously will be. It seems I've read several cases now of a developer or playtester recreating one of their favorite PCs from older game iterations. Very doable. And, frankly, expressing your PC through the available game mechanics in a manner that closely resembles your imagination is a significant part of the fun with D&D.
