Who will make their way for final of World T20?

Now it's final decisive moments for qualifying team for ICC world T20 final.According to current form I think West Indies and South Africa will make their way for final as this two team comprises of world class hitters.Sri Lanka is not favourite among T20 fans because except for two or three player in their team there are no hitters.West Indies's win in semifinal will largely depend on Chris Gayle's batting but they also have Dwayne Bravo who is capable of giving non deterministic
results.Anyone cannot expect that Pakistan will qualify for final.
On the other hand there is label attached with South Africa that they are choker(missing there way in decisive moment).So let us see who will raise ICC World T20 2009 trophy.
