You've got that wrong actually.The ACB put a solution forward,hinting towards swapping series dates.According to the current ICC calender,Australia are to tour Pakistan in March,whereas Pakistan are to tour Australia in September.The ACB has offered to swap the series,and said that Pakistan should tour Australia in March,and Australia would make the return tour to Pakistan in September when the situation in the country has stabalized..Pakistan doesnt like this idea,and they want the series to go according to the ICC calender because of financial losses n shit.Neutral Venues are totally out of the question btw.So even though the series MIGHT be interchanged,there is no way that the series in March would be played on a neutral venue.
