Hooray! Planet of the Ood has now aired, and it was indeed an excitement-filled bucket of joy and danger! Or something along those lines.
We didn't have much mention of anything really, other than another reference to the Bees disappearing. But I reckon thats a good thing... don't want to over do it.
You can now watch this episode on Planet Gallifrey TV
Or here, here, here, here, and here
And, finally, hooray for those lovable, sqidgey Oods! Who's heads (according to David Tennant) "are so squeezable, you just want to bite them."
