The suspense is killing me.
The production cross section of the higgs through the fusing of two gluons mediated by virtual top quarks, which is the dominant one, was roughly 20 picobarns, or 20000 femtobarns. The statistics collected till 2013 was 25 inverse femtobarns. If you multiply, you get that roughly 500000 Higgs bosons were produced. In 2015 alone, 10 inverse femtobarns are planned, but at 13 TeV the production cross section is 2.4 times larger, so roughly the same # of higgs bosons, 500000, will be produced this year if all goes according to plans.
