I've little doubt that as the game formats increase in length so too will the balance and strength of the tourists.
Faster bowlers like Dale Steyn and Marchant De Lange will begin to play their part and we will see the experience and quality of Graeme Smith and Jacques Kallis return to the side.
Morne Morkel was the only bowler of any genuine threat on Friday night and it was pleasing to see the way Guptill and Co dealt with 150km/h coming from a big bloke who delivers the ball from six foot goodness-knows-what. It alleviated a lot of my fears that New Zealand could get caught out.
However, come test time Morkel, De Lange and Steyn as a unit could be terrifying.
It's not test time yet and right now I'm installing New Zealand as favourites to take the T20s. South Africa need to think about bolstering their spin options. Johan Botha is a quality off-spinner but after him JP Duminy appears to be an afterthought for AB de Villiers.
Against New Zealand, de Villiers may be better served to bring in Robin Peterson and try to utilise all three of his spinners - but I bet he has no knowledge of the success the slow bowlers had in the HRV Cup.
South Africa's batting probably offers the most threat over the next two games. Richard Levi looks as if he has some devastation to inflict and, if he gets going, the clever Hashim Amla will provide a good foil.
AB de Villiers is too good not to fire in one of his three T20 innings. Duminy and Justin Ontong showed they are heady players and I expect to see some bludgeoning from Albie Morkel. They have enough quality there to expect Friday night's effort to be their worst and it will need to be - because with the depth in batting firepower the Black Caps have, and the relative lack of firepower South Africa possess in their T20 attack, they will need two big scores to come back in this series.
