With future ODI tournaments in England in 2017 & 2019. These ODI series teams like NZ & Aus play in England this summer do carry some added significance and some context. Not totally meaningless after the Tests are done as the obvious main part of the tour with this being an Ashes summer. Of course the Ashes themselves and the build up to it.

2 years before the last one. 2 years before the next.

Why is it happening in England again?

1) Replaces proposed ICC Test Championship. A format was considered unworkable.
2) 2013 was a huge success.
3) June 2017 is the available window - not suitable for many better countries than England.
4) Big 3 has taken over cricket. Such Events can only be in India, England or Australia (2015-2023).
