They might be tigers in their backyard, but my gut feeling says they can't prevail in the next edition of cricket's premier tournament.
If Indians do well in OZ conditions and hand them down a series defeat later this year, they would be further demoralized as a team and might start disbelieving in themselves.. However, such situation is highly hypothetical, given India's fallibility overseas..
Nevertheless, when it comes ODI cricket, I guess, India, SL along with SA and NZ have better chances at next year's world cup. OZ could face elimination before quarters..
