I haven't read this thread, so apologies if this has been said:
I would rather they make mods rather than scenarios. Think about it: Scenarios are limited to only one map where as mods can have that same flexibility as the standard game does. Imo, most people are put off of scenarios because of their inflexibility. NOW, if they made mods called AfterWorld which had a whole new gameplay style that wasn't dependant on a particular map, then that would essentially give Civ4 a whole new dimension. Add many mods and you'd have many dimensions.
