Yeah I think that's probably true, turnout will probably tell a big part of the story.
I just don't really know what Brexit being done and dusted means in practice. We have reached the stage where nobody in favour will admit it was at best pointless and at worst a disaster, instead they tell you that the government have done Brexit badly and that they themselves would have done it really well, without telling you what that means (and which we also know wasn't really possible because expectations had been set too high by the leave side). I am not sure it will ever end.
