Quoting a source in the Pakistan Cricket Board, The News reported that all four countries have written to the sport's governing body to extend the date so that the bid could be worked out between the sub-continental neighbours.
''The ICC has not as yet responded to our request but we don't see any problem with a delay in the submission of the bids.
Specially when the movers are four Test playing nations of one of the largest regions of the world,'' the source told the daily.
''The heads of all four cricket boards will meet again on March 12 in Chandigarh (India) to finalise the joint bid and before that all the boards will coordinate with their governments and take steps to fulfil the conditions laid down by the ICC with regard to tax exemption, immigration, hotel facilities, practice schedules, travelling, security etc,'' he added.
Meanwhile, Australia and New Zealand submitted their joint bid for hosting the mega event today. The ICC will announce the winning bid in July after examining the proposals in its Dubai meeting.
The source said the South Asian bid is likely to be stronger than others' because of the passionate following the game enjoys in this part of the world and not to forget the lucrative sponsorship deals that can be worked out here.
''The following for the game is immense in this part of the world and the sponsorship and marketing opportunities are also varied compared to other countries. Imagine the TV viewership figures in South Asia,'' he said.
India and Pakistan have co-hosted the event in 1987 and Sri Lanka joined the two in hosting the 1996 series. Bangladesh has been added to the bid this time, paving the way for a four-way distribution of matches.
