It will be interesting to see where they take the story. I hope it goes in a intelligent direction.
The Jem'Hadar fleet is expecting a war with the Alpha Quadrant and Cardassian allies near by. Once they realize this isn't going to happen (aside from the True Way faction) what do thy do now?
Like Scout said the war was 30 years ago they should figure that out rather quickly.
And doesn't the Federation have the female Founder is custody? That alone is enough to stop any further attack. We have their god as a hostage.
As it stands there are a lot of quick ends to this story line.
