You think it will take two years? Well damn I'm hoping we get dlc and stuff sooner.
Anyway what I'd like to see now is some additional fluff to cover upgraded units. The basic soldier fluff doesn't make much sense when you start racking up affinity levels.
In the near/mid term? I'd like to see more units. Not just affinity units but basic stuff like apcs, transports and vtol gunships, more infantry units and so on.
More aliens would be nice as well. Hell maybe introduce faction specific units....
Additionally more stuff on the planets. The tilesets are okay but could use some more variety and visual oomph.
More factions would be nice too.
