First Impressions and Some Questions

Hey All!

I just finished the campaign and I thought I'd give a few first impressions.

After having bought (but never really played) the first game, I got this one for free. Judging from my ~ 5h of playtime my first impressions are the following:

- The UI is hugely improved, but not perfect

- Encountered some bugs but nothing game-breaking

- Tactical Combat is a lot of fun now (and it is actually possible to apply tactics)

- The campaign is fun, well-written and provides a great introduction to the sandbox-game

- The campaign is tooooo short and the link in the credits doesnt really help

...

- Overall I have to say that it's a huge positive surprise for me and I am looking forward to trying the sandbox game soon. But... seriously the campaign is too short

Which leads me to my questions:

 I didn't follow the game at all for more than a year, so I have no clue basically... What is the plan regarding the development of the game now ? Will there be expansions that focus on continuing the campaign or providing new (longer) campaigns? Will there be multiplayer ?

(I realize that actual implementation will depend on sales. I guess I'm asking for the "vision")
