Thanks for bringing this potential mistake to our attention. But, after checking with all our experts in the lab, there isn’t really a mistake.
Indeed, the review was a bit harsh with the new version of the Canon EF 70-200mm f/2.8L IS II USM and we modified it: http://www.dxomark.com/index.php/News/DxOMark-news/Canon-EF-70-200mm-f-2.8L-IS-II-USM-measurements-and-review.
But, overall the Mark 1 has a slightly higher and more homogeneous resolution. So, it scores better on a full frame camera, like the Canon 5D Mark II used in the review.
But, as we also added to the review, if you make the same comparison on a APS-C, it’s the Canon EF 70-200mm f/2.8L IS II USM that comes out slightly ahead. This may be the reason why the results are in other reviews made on other cameras.
So, what it means is that both lenses are really really close, and if you have a full frame it is better go for the older version and if you have an APS-C the newer version is a better choice.

dpreview, Imaging-Resource, photozone puts the new 70-200/2,8 ahead of the old one , tested on APS or 24x36mm
