So far they have some Old West stuff (including a mariachi band!) and the colonials. The colonials are all for the third Anglo-Burma war (circa 1875) and include Brits (with and without mustaches and in glengarry). I think Indian troops are either new or soon to be released. Sorry not to be more specific, but my catalogue is at home.
So far every colonial range seems to consist of five packs of four figures each broken down into two variant command packs (with officers, NCOs, and musicians) and one each of other ranks skirmishing, advancing, and charging.
