that humans are being taken from Beach City because Steven and Greg's Zoo earrings led the abductors (whoever they may be) there in their search for Greg?

that Holly Blue spilled the beans about the Crystal Gems infiltrating the Zoo, and the Diamonds are now on to them?

I was beginning to think I was the only person that around here that understood the difference between a hypothesis and a theory! To add to your hypotheses:
 * I may update this comment with more hypothetical suggestions based on the promo (which was awesome).

1.  They do look like water wings, though they look like they have globs of something in them (unlike Lapis' wings).

2.  Yeah I would not doubt that the earrings act as tracking devices in addition to functioning as a way to communicate instructions to the zoomans. However, Homeworld knows where the CG's home base is without needing the earrings to lead them there. It could be a little of both, I doubt they would go through the trouble of showing Steven keeping his earrings without it leading to something later. Checkov's gun and all that.

3.  I think Holly Blue would only spill the beans under pressure, which I am sure she received. If I had to guess I would say that Navy went back to Homeword and gave them a full report. Even if Steven did not talk to Navy about the zoo, Navy would have told about the CGs using the ship. If the ship has any sort of flight recorder and/or the zoo facility logs the ships as they come and go, Homeworld will know that they had been to the zoo and would start putting the peices together and question Holly Blue.

To add to that, we don't know if Navy knows about the Steven/Rose situation, but if Navy picked up the rest of her squad on the way back then the diamonds have an eyewitness to the fact that "Rose" is still walking around uncorrupted, albeit in a non-standard form. Steven was quite vocal about wanting "my dad" on the ruby ship and in the zoo, and probably talked about "my dad" to Navy. Assuming the diamonds realize how important "MyDad" is to "Rose", they could be looking for Greg not for zoo purposes, but as an act of revenge, for leverage to get Rose to give herself up, or trap her in another rescue ateempt. Zoo specimens are a bonus.
