Yes I tend to agree, some persons must be please to hear of his absence for the ODIs. Like you I do hope he plays the 3rd and final test, it would be a fitting end to a super series and a great start to 2009.
As for the ODIs themselves, last year his absence in England did not help SA at all, however I will venture to say that they are an improved team since then, so I wish them well.
Its interesting that Prince is not part of the ODI team, one would have thought that with Smith being out they would have put him in. Also this guy Johan Botha the captain, the few games I have seen him played, there is not much to him, his ODI debut was back in 2005, but finds it difficult to be part of the ODI team full time, am wondering if they are grooming him for captaincy in the future, with Smith elbow problem, who knows how much longer he can stay playing the game (for the sake of the game I hope 10 more plus years) but you just never know with these injuries.
