of course if the format is somehow adopted, each team would provide a list of prospective venues for at least 5 years in advance.
the politics of it make the thing difficult, not so much the logistics.
There should be a team match every year involving the three rosters: USA, Europe, Rest of World.
The loser of this year's match doesn't play the next year. Simple as that.
US - Europe next year, the winner plays the RoW in 2017, the winner plays the 2016 loser in 2018 and so on. Loser leaves the table (and the TV money).
Host should alternate, of course. This will solve also the fiasco that was the EurAsia cup project.
