OK look I'll start by saying I loathe the Generic realms, its personal opinion but I can't stand it but since the devs have clearly said their focus is FR right now please at least give me my two favorite characters (well one character and one family) Regis "Rumblebelly" the Halfling Rogue and the Harpell Family
It could be ALOT of fun with a quest involving the harpells zaniness and tendency to "experiment" with magic. Not really sure what you could do with Regis...but please try
Sidenote: Please if its at all possible don't do anything with Drizzt we already had an epidemic of Not-drizzts when drow were released and we don't need to encourage that again not to mention imo he's one of the weakest FR characters. That said if you insist on doing Drizzt (because I know you will) please include Jarlaxle as a big part (and not just as a villain, hell I wouldn't mind woring WITH him)...I loathe drow but this guy I actually had some respect for.
Sidenote2: I'd still rather you forgot about FR and returned to Ebberon but I've I doubt WB will let you waste the X amount of $$$ they spent getting the rights to that setting especially since they probably want to compete with NWO (which they don't have to..horrible game FYI...its not dnd at all...it could have a completely different name and no one would have noticed)
