Now after watching current series and few next years visits any one can predict that first final of WTC is going to be played between Australia vs India as both right now on top and for next few months they can mainatain their lead and can stay at top of list no one going to challenge them.
I would add New Zealand as well. their WTC schedule seems easy because they are not touring England and South Africa. England is excellent in the home condition and South Africa tours are always tough for any visiting team in comparison of Pakistan (UAE) Bangladesh, Srilanka or West Indies.
