GB should dominate in London. They'll have a big team and home turf. They should beat us every time really, given the amount of money they pour into their athletes and the size of their population.
Don't count the chickens early, HJ....I seriously think Great Britain will overhaul us Aussies in the medal table, they have been gaining more and more prominence in more sports...including swimming, cycling, rowing and triathlons, plus the usual athletics.
