Last Dev Stream we saw how we could make custom races. So, as an avid modder already toying with preliminary ideas in a spreadsheet, I have a few questions (and perhaps others will add to the list 
):
Can modders modify traits?
Can modders add more traits to the game?
Can modders modify abilities?
Can modders add more abilities to the game?
Is it possible to create custom races without abilities? Are the abilities hard limited to two per race? (To throw in a bit more realism, not all AI races have to be equal... right?)
And...
Where is Colonel Jena Casey? Is there a new animation yet? (Or at least a teaser?) Since D.L. Bradey seems to be the guy returned from the pocket universe with the First Fleet, and Jena"s leading the Patriots of what's left of the Second Fleet, who is leading the Mutineers? Any art for that person yet?
I ask because having more than one animated human leader would be fantastic for modders to create their own custom human factions...!
