I was a little disappointed that no significant mention was made of the game AI and how it can be made more efficient, or its workings separated potentially outside of the main game thread. More units is a challenge for the client side to be sure, but even if you could render a whole airland battle, it won't bring you much joy when the gameserver chuggs to death because a script asked some armoured units to move to a town across the river and pathfinding exploded. Ditto considerations about running IADS, although there has been movement on that very recently.
