Depends to me on whether there's an actual regional presence. If there is, then it should be reflected in ccTLD sites. If not, I certainly wouldn't use ccTLDs to broaden a base that's in fact there only for imagined benefits of promotion.
That would be like putting up a directory of US cities on a widget site to target more local searches for widgets. It generally doesn't make sense to do that, unless there's actual local content that's really unique to the locale.
I see that with ccTLDs in the future, the bar with regards to genuine local presence will be raised higher, with things like local links and perhaps local hosting) becoming larger factors. I think that from the beginning, localization of local content on foreign sites has always been a factor.
Certain spellings might change... "glamour in the theatre" is different in the UK than here (probably beyond simply spelling ;) ...Addresses, phone numbers, etc, are obviously the lowest hanging fruit for changes.
