The two sides played out an oft-heated test series this summer, with Watson and Warner involved in plenty of verbal spats.
Warner has kept a lid on things since being fined for demanding Rohit Sharma speak English in a one-dayer at the MCG, where Sharma insulted the Australian in Hindi.
Sharma, who scored a century in his side's quarter-final win over Bangladesh, promised there would be no let-up in India's aggressive approach. "If there is a bit of banter going around, so be it. It's part of the game ... I just hope it doesn't cross the line."
Australian captain Michael Clarke agreed there would be sledging in the match, but noted it wasn't a focus for his side. "It's really important we focus on what's important and that is playing our best cricket," he said.
ICC chief executive David Richardson said: "Things get heated; we actually like them to get heated from time to time."
