I guess a war with the Klingon Empire was moved forward quite a bit. The events in the movie make a pretty good political reason for the Klingon Empire to go to war -- humans illegally landed on homeworld and killed dozens of warriors and knocked out a few patrol vessels.
I bet the next movie is about such (Enterprise will be recalled).
I hope not, or at least ends with some kind of peace.
I also found that moon around Kronos interesting, it really did look like Praxis but it looked like it'd exploded already.
