Stories about the new coat of arms can be found at http://www.dailymail.co.uk/news/article-2087966/Donald-Trump-wins-right-use-family-crest-Scottish-heralds-advertise-golf-course.html and http://www.dailyrecord.co.uk/news/scottish-news/2012/01/18/donald-trump-comes-up-with-official-coat-of-arms-to-go-with-750m-golf-resort-86908-23705556/ and http://www.deadlinenews.co.uk/2012/01/17/donald-trump-at-last-awarded-the-scottish-coat-of-arms/ There are, no doubt, more stories about this on the websites of any number of newspapers.
Additionally, folks have been making proposals for what the new coat of arms perhaps should look like. Here's a couple of examples.
The motto for this one is Latin for "You're fired."
And the motto here is Latin for "Keep your hair on."
