You are right Michael. If Scotland votes Yes then it will also surely signal the end of Great Britain (a term which was only introduced with the Act of Union). Which, incidentally actually means Big Britain to distinguish it from Brittany - but lots of other people, including many eminent politicians, give it much more baggage than that so as to imply Great meaning fab. Big psychological blow indeed.

That all said, no point worrying about it until/if it happens.
