I expect that Scotland will say NO this time. They are threatening all sorts of new weird stuff if Scotland tries to get away from Big Daddy. No Pound currency? No Coronation street?. no BBC. People and businesses diving to get away from Scotland. All sorts of stuff that nobody knew about in 1979.
1979 result below.
The result was a narrow majority in favour of devolution. However, Parliament had set a condition that 40% of the registered electorate should vote "Yes" in order to make it valid. The amendment to the Bill which set this condition was moved by George Cunningham, the Scottish-born Labour MP for Islington South and Finsbury.
Thus, despite a turnout of over 60%, devolution was not enacted since less than 40% of electorate voted yes.
