If its down to a vote amongst test-playing nations then obviously thats four votes to the subcontinent, NZ and Aus would vote for themselves, England i think would vote for Aus/NZ as would Saf, In the New Zealand Herald the other day Chanderpaul said he'd like NZ to host the tourney so that looks like Aus/Nz bid would be succesful, not sure if Zim would vote as they suspended their test status i think?

Although if it's like the rugby world cup process, the bidders cannot vote so NZ/Aus bif would have it on a plate.
