Yes, I remember the debates from a while ago, I just didn't see any progress or decisions yet. And while I think modding is nice, I am not interested in learning all the interesting things that I could mod into the game; I want modding to be for new exciting races, new graphics, or radically new rules.
I could mod many things into GC2, and I still didn't like the way that each unit was, basically, the same.
I am interested in the way the basic ruleset of the game will differentiate between units. I find the combat in CivIV to be more interesting, so far, than what I see under the hood here, because CivIV has unit types.
Think of it like this, if you want: You can make an RPG with classes (like D&D, or Dragon Age): these classes are disjunctive and each member of the class has special abilities. Many MMORPGs are like that. Or you can make a classless system, like e.g. Arcanum, or the HEROES system. If you choose the latter, you will need a robust and differentiated way of assigning abilities and attributes, for balance reasons. I think Elemental is in danger.
I think Elemental is in danger of going the latter path (classless system) but with the mechanical paucity of the first.
