I really think it could be. With the majority of the grounds in the caribbean likely to be fairly small, pitches very batsman friendly & the increase in scoring rates amongst the top sides which i think has been helped by the introduction of 20/20 cricket which has lead to some big scores in one-day cricket over the past 18 months or so.
I really think we are going to see some really big scores next year amongst the major nations due to those facts, the caribbean IMO looks tailor made for aggressive batsmen & the top 8 nations once they go full-strenght have very strong batting line-ups.
So for me, i think the winner of the world cup will be the sides with the best bowling attack, and IMO Australia/South Africa/Pakistan have the best all-round bowling attacks in One-day cricket to bowl in most circumstances especially in the crucial death overs, so once they have all their best players available i strongly believe these three (3) sides have the best chances of coming out victorious next year. But overall i expect next year to be the best ever.
