Since a lot of the talk has been about DRS above, I will like to chip in with a point. The truth is that Umpire's call makes no sense for one more reason.
For instance, in an LBW decision the Umpire knows the ball is hitting the stumps only partly and not full on, just enough to return an "Umpire's Call" on review. However this is not an issue for the Umpire, he knows the ball is 'just' hitting the stumps, and if that is the only issue he would give it out. However the issue is he is not sure if the batsman was struck in line of the stumps. The Umpire is of the view that the Batsman was struck outside the stumps, and if he believed that the ball struck the Batsman in line he would have given it out, even though the ball would partly go on to hit the stumps.
The Bowling side reviews, and lo and behold, the Impact was slam bang in line of the stumps, but then the ball is show to 'just' be hitting the stumps and 'Umpire's call' is returned, hence the Not Out Decision stands. This is now ridiculous, because the basis of the 'Not Out' was not whether the ball would 'just' hit the stumps, but whether the Impact was in line or not. The Umpire having seen that the impact was in line, would give the Batsman out, the basis of the decision was where the impact was and not whether the ball would hit the stumps, but he cannot, because there is no provision to explain what he was basing his decision on to the person making the review, the Third Umpire.
In a decision where there are three grounds to consider 1) Where did the ball pitch, 2) Where was the impact 3) Would it hit the stumps, on which of the three grounds did the Umpire rule Out or Not Out is important. Without knowing this just blindly returning an 'Umpire's Call' is ridiculous.
In the above example, the Umpire would have liked to review whether the impact was in line of the stumps or not, and having seen that the impact was in line, he would have ruled it out. However the DRS, which will show the impact was in line, will just plainly assume that the Umpire already knew this and doesn't have any doubts on this part, and will let the decision Not Out stand on the ground that the ball was only partly hitting the stumps, Which the Umpire knew and was fine with, and which was never a ground for him ruling the appeal as Not Out !!
That is DRS for you !!
Okay onto the test itself, I had thought that it would be a 5-0 whitewash but on the basis of the 1st session I am willing to reconsider that. What a waste of a pitch !
