The House of Representatives could barely pass something relatively uncontroversial like the farm bill. I personally don't see them tackling this highly contentious immigration bill anytime this year, so DV 2015 entry month is very likely to take place. However, if by some miracle the bill is passed before May 2014, they might instruct the Dept of State to cancel it and not announce the selectees.
I think this immigration bill is going to drag on for some time. The Democrats and Republicans are going to squabble endlessly over it before they reach a middle ground or agreement on what should be done.
I think there will most likely be a DV2015 and perhaps if they're feeling nice, they'll let it through as the last DV if they decide to cancel it but then again I may be mistaken as I'm only guessing.
