BtS using Ethnically diverse units mod?

Anyone know whether Firaxis is using ethnically diverse units mod by Rabbit White or they have remade by themselves the look of all units?

There are unique looking units for some civs and/or civ groupings, and some of these were fan made.

edit: gamespot mentions unique swordsmen, and that they are more for the early game.

They haven't said anything about including RabbitWhite's mod. Since they have lately been very open in naming the mods that are part of BtS, but haven't mentioned RabbitWhite when they talked about the new diverse unit functionality, they probably didn't use his mod.

Also, they are talking about just a few units being ethnically diverse, not all of them. They talked more about the new functionality itself (i.e., allowing different looks of the same unit, which eliminates the need to create lots of differently looking units with identical stats) than about the units that actually use it.
