And if they did decide to get both, they'd end up fairly close to the current situation, but without a vote in EU matters. It's possible the Leave campaign may have mislead the voters on this point.
Two and a half years is a long time, you may well find that enough people have sort of forgotten about EEA free movement of people requirements by the time it comes to actually leave EU and gain membership of EEA. Remember, 'enough people' is only about 500,000 or so, and that will be in the context of a general election.
50% of the UK is flat out opposed to freedom of movement. In fact I'd wager it's even less than that since freedom of movement wasn't the only talking point of Leave.
The other big issue was the money we pay to Europe which was exaggerated; has the falling pound wiped out that 'saving' yet?
There are many treaties between Switzerland and EU, and after they slammed the door I just don't see EU countries accepting the same deals with UK.
I recently visited the swiss/french border region around Geneve. I can assure you that english was not really a good option for communicating there outside of airport.
