Yes I've noticed that too. Have to say that I'm struggling to really get into the event, which wasn't the case in Beijing.
It must seem strange for them to come back to Wimbledon after only 3 weeks. It would probably have been better for it to have been on hard courts to give it the feel of being a new and separate event, but of course it would have been a waste of money to build new courts just for the Olympics. Vera Zvonareva commented about how it doesn't feel like they're in the Olympics because of the Village being so far away. It's not like they can really go to any other events to watch, unless they want to be travelling for nearly an hour each way, and likewise other athletes can't really come to see the tennis either.
But Andy does seem to be taking it seriously, and if the top players progress in the event I'm sure things will liven up towards the end of the week.
Thank goodness I'm not alone here. I'm finding it hard to get into the event too. Wimbledon will always be just that no matter how much they try to change it cosmetically - and it doesn't help either that the venue is still called Wimbledon. It's quite bizarre really, but I realise there's no other option. At least Andy seems to be happy about it, and that's the main thing.
