According to the British "Sunday Times" report on July 1, the publicity buses that are currently in operation have already been painted with the improved Olympic logo on one side, with a child in competition appearing among the scattered digits of "2, 0, 1, 2".
The news was obtained from 163 (http://news.163.com/07/0702/02/3IC50II70001121M.html), but the official website of the London 2012 Olympics has not yet been updated with the improvement.
