There will def be a temptation to make it more harsh. UK won't get a better deal, it will get a different deal. It's apples and oranges, thus, it'll be hard to make a comparison between the "new" and "old" deal. However, I feel that EU leaders won't have to make the negotiations harsh - the self inflicted damage will be big enough as it is. Of course, I might be proven wrong and the UK might thrive outside EU. Time will tell.
