Canon 5D Mark III low light ISO samples on Dpreview

I agree, first i looked and thought it looked really good at high iso's but then i didnt see any chroma noise in the shadows and wondered if it was with nr on or off but couldn't find any info on that. Now ive looked closer and I can see that it does have pretty heavy nr because of the smearing but ill wait to see any raw samples before i make any definite conclusions on whats going on.
