Why South Africa next Year ?

As a very good test playing nation at the moment, shouldn't we be playing South Africa over 5 tests?

I know it would usually be 4, but because of the Olympic games they are having just 3 ! 3 against a really big test playing nation, one that is also vying for that no 1 ranking.

2 points. 1: Why not play the Windies & New Zealand next year ( 3 tests each)
2: So what the Olympics are on ????????? There are loads of test venues north of the Watford gap why noy at least have 4 tests ?

I understand it can't be in 2013 as it is ashes year, but am i the only one who wishes that test series was over 5 matches as it was in 1998 ?
