The future now depends on the whims of the EU leadership, who may decide two general courses of action:
1) Punish the UK, properly shaft it, and hope that the fallout somehow benefits the Eurozone (it won't though)
2) Try to exercise some damage limitation by allowing the UK to continue some kind of special relationship with the EU by remaining in the EEA and therefore an active participant in several core components in EU policy (seems less likely to me, but surely what the UK leadership want, not that they'll have any say)
