IMO there will be another referendum anyway, so we'll see how many have changed their minds.
Let's face it there really are only two options. "Hard BREXIT" or Remain. "Soft BREXIT" would only mean us paying for access to the single market for worse conditions, that being accepting free movement and the ECJ etc without a seat at the table, or a voice in the European parliament. That would be ludicrous.
So we're left with this minority government trying to push through a complete exit, which they won't be able to do as there are far too many remainers, on both/all sides, in Westminster who will oppose it, which will therefore lead to a 2nd referendum to get their plans ratified.
Then we either vote to walk off the cliff, or we stay in. But at least we'll all have a better idea of what we're actually voting for!
The GE result has basically guaranteed a 2nd referendum. The rest of the intervening 2 years is just very frustrating foreplay.
