Why'd you shrink down the images? It kinda defeats the point of a comparison such as this when you've scaled both shots to 867x487, and the supposed resolution of the 360 version is 1024x576.
From what I've read on gaf, the analysis of the available screenshots was done properly. The only question is the source of the 360 shots. I'd wait until after both versions of the game are readily available before trusting any comparisons like this.
