Japanese site Digital Life Innovator (translated) posted a new set of sample pics shot with the Canon EOS 70D and an EF 60mm f/2.8 Macro lens (more sample pics by the same site can be seen here). Original files can be downloaded. Image quality is pretty amazing, especially for the high ISO shots (see pic above and below, both shot at ISO 3200). Korean site DicaHub (translated) posted test series covering the whole ISO range (100-12800), with additional crops taken from each test picture. More after the break.
The test series by DicaHub also shows that image quality (noise-wise) is very good up to ISO 3200. See pics below and have a look at the original post, since there is much more too see (including a comparison between video and pictures).
