The last two World Cups in 2011 and 2015 were won comprehensively by the host teams in India and Australia respectively. What is more interesting is that their opponents were their neighbors- Australia and New Zealand 2015 and in 2011 it was India and Sri Lanka. So, it was money's worth as the audience got to see their local superstars in the Main Event.
Will 2019 continue to march in favor of the home team? - this time England -who have never won a World Championship of this magnitude, excepting Champions Trophy 2004 and World T20 2010. But if there was ever a re-birth needed, it happened to the England limited overs team, and it was of some measure. Since the 2015 debacle, they have done what no other England limited overs outfit has done in over 47 years and pipped India to be No 1 in this format. The World Cup returns after 20 years, though in the interim there have been a few World T20 Championships and Mini World Cup tournaments.
Australia with 5 championship titles, will look for a record 6th and it will be helped by Smith and Warner's return who have been grounded for one year. Pakistan will want to prove that the 2017 Champions Trophy (mini world cup) after a disappointing start and an exhilarating finish- was just a preview in lot of ways.
India, under a new captain will want to win so as to make a grand homecoming after 36 years to the country where they got their maiden title in 1983. 4-time semifinalists South Africa will want to at least enter one final for the gold quest. A few teams have been close but not enough so as to win the tournament, while others have been the favorites all the time. West Indies just literally crawled into the tournament while Afghanistan who has nothing to lose could play spoilers for the big teams. Each team will get 9 opportunities to get into the knockouts and laxity will be a bane.
