One thing is for sure: UK won't be acting like a spoiled brat anymore, as it did while it was in the EU. So they'll probably take whatever deal the EU throws at them. And if the EU people are smart, it won't be a great deal either, otherwise it could encourage other such exits. EU's #1 priority right now is to stop other countries from exiting, not ensuring a "smooth landing" for the brexit (for either UK or the EU itself). Those two goals are actually in complete conflict. The harder the brexit will be on UK, the easier it will be to convince other countries not to exit. The opposite scenario is also true.
