If people think the UK might start bleeding parts in the next year they would be expecting a lot, but the big question here is what will Brexit mean for the long term economy of the UK? The EU? The world? If there are serious economic repercussions, opinions very well may change. 

That's the crazy thing about what is going on here. There are no certainties. Britain just rolled the dice, and all anybody can do is place bets and hope they get lucky. We can only hope Britain gets them some good trade deals and the EU uses this opportunity to reform, and the economy takes it all in stride.
