More technological advances. Apple will release something that everybody will love but no one will need. Greece will be recovering...maybe. Britain will have declined but not as much as people expect. Spain will still be economically a mess.

Brazil will have finished getting itself together after the economic mess of the Olympics. Germany and Italy will both be closer to gay marriage. Yeah Portugal will just remain useless unless we're talking about football. South Korea might start CONSIDERING to allow gay civil unions. Japan will have to get serious about their population issue. Nigeria will grow economically and start to have more of a presence on a global scale. Cuba will grow due to new American tourism.
As for the US...
Hilary will run for her second term and a third party candidate will become more prominent, probably won't win though. The US will have done nothing about gun control per usual (thanks NRA). A movement against ableism will be on the rise (a milder black lives matter tea). Our economy will be on the rise after experiencing a drop due to Britain's exist. I have no predictions for foreign relations in regards to the middle east (that's gonna be a **** show).
