In the past it was West Indies, England and Australia who were the big boys. Now it's India, England, Aus and SA who are the big boys.Sadly there's not enough of a monetary incentive for the larger nations, particularly India, to do such a thing. India have yet to host Bangladesh in a home Test series ffs - there's more chance of me hitting the winning century in the 2015 final than there is of the richer nations hosting Ireland.
FTR, SL did not play a Test match against WI till 1993. Go figure
Everything boils down to $$$ at the end of the day.
