Some of the nonsense in this thread is rather worrying.
By simply doing a little research one could easily see the plans not only for 2010, but also beyond. Public transport, such as the BRT systems are currently being implemented in Johannesburg and Cape Town. Maps are available to the public detailing the different phases of development and when said phases will be completed.
The stadiums too haven't simply just been built. Immense planning has gone into their feasibility. Plans have to be presented to cities by stadium operators detailing how they plan on running the stadiums and how they will ensure that they are not white elephants. There are countless opportunities to not only host matches, but also concerts and other large events. The people running the show, believe it or not, actually know what they are doing.
Lastly, improvements can't simply grind to a halt after 2010. Thinking like that is very naive. Contracts have been signed, plans have been put into place (at a cost), preparation have been made (once again at a cost) etc. Let's take the Gautrain for example...all the stations and routes have been planned to completion. Some of these stations will be incorporated into huge developments, such as Zonk'Izizwe (which will be a new mixed-use precinct including the largest mall in Africa). Other large developments are planned for after 2010, but have already been started. Sandton City, for example, is undergoing expansion. What's coming after 2010? A new 80 floor tower, which will be the tallest skyscraper in Africa (and very sexy might I add).
2010 is not the "enemy," as so many people seem to believe. It is in fact forcing government to get its ass into gear and deliver. The negative attitude of South Africans is really disappointing. Yes, government may be incompetent in so many ways, but there is just as much good being performed in the country at the same time. Just look at how the Cape Town CBD has been cleaned up, how it's getting a shiny new skyscraper, how it's public transport system is being overhauled etc. Johannesburg's inner city charter plans to have all delapitated buildings refurbished by 2014.
Seriously, some positivity for once would be nice. We have a way of digging ourselves into a negative hole we can never get out of. Just like the media in the US, for example, only shows Americans the worst news about South Africa (causing many of them to think we have lions in our back yards etc), we tend to focus on the bad news and not appreciate what we do have. There are not many countries in Africa who would have remotely been able to pull off an event like this, and countless times in the past have the media complained about the stadiums not being ready in time etc, yet look at them now. They're completely mum when many of the stadiums are ahead of schedule.
