Well I'm no expert but it sounds to me like you had a swarm!
This means the original queen with a good percentage of the bees is off making a hive somewhere else, and they left behind a ton of queen cells so that one queen will win the hive. After the queen emerges from her cell, it could be up to about 2 weeks before she's mated and laying. That means there's 2-4 weeks where no queen is laying, so of course you won't see any more open brood--it was all capped over shortly after the queen left with a bunch of the bees.
People say swarm queens (the ones created and left behind) can make the best queens. If the last of your capped brood is hatching, that means the old queen was laying about 3 weeks ago. I'd check the frames real well in a couple days to see if there are any eggs from the new queen--she should start laying this week or early next.
Best of luck with your new queen!
