Australia - team too inexperienced. all their best t20 players have retired from the national setup. rest of the team has skipped the IPL, this years tournament will have less of a "winging it" feel than 07 and australia may be out of their depth against more practiced countries.
Bangladesh - same old in every format. no chance.
England - have looked badly out of touch with the format. can't see them doing it.
India - definitely got the best pool of players to choose from. will they be able to make brave decisions like in '07 though. their current international setup was culled from that 07 team so it will likely feature the players we've been familiar with over the last 2 years. but could leaving ojha, jadeja, nehra and the like, proven IPL performers backfire?
Ireland - small hope, pity they don't have morgan as it would be a fairly decent team. still will struggle as no one is going to score a 25 ball 50 in their side or just go that extra inch that seperates teams.
Netherlands - no hope. though seeing nannes bowl for them will be entertaining. batting is as frail as meringue though.
Newzealand - have a few T20 experts but lack a balanced team. Taylor finding form right now might boost their chances. You feel the batting is always going to be weaker than the bowling but they should be solid.
Pakistan - blessed with some of the best t20 players in the world. maybe a bit out of nick not playing the IPL but killing australia put rest to the idea that the game had moved away from them. probably the best bowling line-up in the tournament if they're on form. outside bet but their stars will have to hit the heights.
Scotland - clear favourites. new captain will provide this unit of men a renewed sense of belief and it's unlikely anyone will be able to stop the slaughter when their batsmen take to the crease.
Southafrica - ab and duminy are in great form. smith, gibbs, prince, botha, their line-up is quite tasty. probably the best balanced side in tournament. of course being south african means they will be vulnerable to inexplicable batting collapses and heinous bad luck so I wouldn't put them as clear favourites.
Srilanka - should definitely improve on last editions performance. Jaya and murali have got the hang of the format, malinga is bowling like a demon, dilshan is really finding form. not bad when your biggest form worries are sangakkara, jayawardene two of the best batsmen in the world. they just need to fill the gaps intelligently. whether that's with youthful enthusiasm (matthews, udwatte) or more reliable players from the international cricuit (kandamby, samaraweera) I don't know but it could be crucial.
Westindies - look horrible right now in england but they have looked at ease in this format. Gayle remains the only man to have 100 in international games in t20 and the reason for that is he's made for it and will take the game away from anyone. bowlers are solid, fielding has looked good, if only in the shorter formats (because it's been crap in the tests) and there is just enough batting their to threaten, though I hope they go with someone other than lendl simmons opening. he's definitely a potential in the test team but too slow for limited over cricket.
