The issue next summer is that because of the Olympics, there will be only 6 test matches and if there are 2 Lords games and a game at the Oval - then half the test matches will be in London - which even as a myopic champion of the 2 tests at Lords and a test at the oval every year can see is unfair on the rest of the country. In my view the fixture should go to the place where there is the highest possibility of a full ground for 4 days... and that wont be cardiff
