Australia - Unlikely, have Warner and Watson, but no much after - Decent pace attack, no spin options which are vital in Sri Lanka
England - Without Pietersen, their batting seems weaker. Morgan is good, but no enough explosive batsmen. Strong bowling attack, but yet to shine in a world tournament
India - Strong batting, but not the strongest pace attack. Have lots of spin options who will be economical.
Pakistan - Not enough substance in batting, although very strong bowling attack
South Africa - Very good all round, but tend to choke in big tournaments. Expect Amla to shine
West Indies - Team of T20 specialists, but do they have the consistency and ability to cope under pressure?
Sri Lanka - Dependent on Malinga, but good batting line up
In my eyes, the favourites coming in to the tournament are the Asian teams. Although India may not be firing at the moment, the IPL has given them a lot more options. Pakistan, India and South Africa are my favourites, in that order.
