The Visa office have published the official numbers of visas issued per country (organized by region). These numbers include Consular processing cases and adjustment of status.
The numbers show conclusively that EU was allowed to exceed the quota by 2000 visas, with Asia and Africa under filling the quotas. Frankly, last year seemed chaotic and many people were extremely unhappy and disappointed with the visa bulletin. However, KCC and the embassies gave a HUGE push at the end of the year to get as close as possible to using all the visas.
If you are interested in seeing the numbers (along with numbers from previous years), you can get the data here.
