Do you think new civs will be added after the release of the DE?

I just saw the poll on this sub about which civ we would like to be added to the game. I sure hope they will add some, but I didn't see anywhere mentioning they were planning on doing that. I know that doesn't mean they won't, but I just wanted to know how likely you think it is that they will add new civs.

Did they add new civs to AoE2 DE after its release? I played for a while after the release, but I stopped after that and I don't know what was added in the updates.
