Cindi --
Hello fellow London traveller!! My UKC husband and I are nearing interview time ourselves. I just wanted to check with you -- your timeline says you filed for K3, but you posted this in Direct Consular Filing -- are you actually filing for the IR1/CR1 as I saw no mention of you filing a I-129F with your I-130... Won't make much difference in interview dates (if at all) but I'm just curious!
We sent back our Packet 3 (which is the the DS230 and the checklist for readiness for interview) on 26 April, and we got a reply from the Embassy with the interview date around 3 weeks later (this is known as Packet 4). It showed our date was on 19 June, which was about a month after we received the letter. Have a look at my timeline -- we also filed in January and we filed for the CR1, as Bruce and I have been married for less than 2 years.
I have heard anecdotal evidence that for people applying for the IR1/CR1 (the immigrant spouse visa), it takes about a week or so longer to get your interview date than if you filed for the K3 visa (the non-immigrant spouse visa, where you adjust status after you enter the US). In general though, expect that the big day at the embassy will be about 6-8 weeks after you send in your checklist. Other London VJers are getting dates right now for anywhere from the 3rd week of June to early July. Have a look at this thread for an idea of where things are now:

They will direct you to their premium rate Visa Info line, which costs £1.20/min and is known over on the UK sub-forum as the Extortion Line. They often don't have all the up-to-date info anyway. If you really want the latest, try calling the Department of State in Washington on (202) 663 1225, and get through to a human. Have your husband's case number ready, and ask them where your file is in the system. When I thought our interview date was lagging, I called quite a few times, and they were always helpful.
Don't worry about biometrics right now -- not applicable unless you've applied for the K3, and your husband won't have to do them until he adjusts status over in the US. If you've applied for the IR1/CR1, he'll have his fingerprints taken at the interview.
It really does seem to lag between sending in the checklist and getting your date, but trust me, it will be there soon! If you sent it on the 10th, even factoring in the long weekend now, you should get your date sometime next week. So much of this is hurry-up-and-wait, but you're almost there -- just hang in there a few days longer!
