Sorry but I do not agree with some people in here, raevsky for instance.
It's too early to assume that someone's chances of getting a visa are close to 0 based simply on their Case Number. Clearly more people were selected this year but keep in mind that the Department of State surely knows what they're doing.
To everyone with a high case number, chill. Most of you will get your chance, and if you've seen a case number 10k bigger than yours, then surely you will get an interview appointment (i.e. for the guy with 42k, knowing there's a 50k case number for Europe)
To the rest, enjoy your summer. You will only be able to kind of predict what will happen starting with September, when the Visa Bulletin will include cut off numbers for October. Stop worrying about your case number, it won't do any good. I was worried too, for so many months, having a case number of 23k out of 30k for Europe, i too didn't think I stood any chances moreover when people on forums were all freaking out. I am having my interview in 2 weeks though and I'm sure everyone will get current this year.
You should worry only if your country is known for having a lot of applicants/selectees (Ukraine, Uzbekistan, etc). The real worry should be having all the visas allowed for a country issued (7% of the total). So if you're from one of those countries with a high CN, things may get pretty ugly (see Uzbekistan this year), other than that I think it's smooth sailing.
Good luck to you all.
