EDGE and OPM UK did a preview for the game and had a chance to play the demo. There are 15 scans, see them here: http://finalfantasy-xiii.net/2009/04/06/opm-uk-edge-may-2009-issue-feature-scans.html
There are lots of info on the game, the series and the jRPGs in general, but most notably is that both magazines had to say about the game's graphics:
'This might sound like the artisan's hyperbole, sugar-coated promises of a creative neck-deep into his current project, unable to get any sense of sober perspective. But as we sit down to a demo of the game, which presents the same 30 minutes of play that will be bundled with the special-edition Blu-ray release of the film Final Fantasy VII: Advent Children in mid-April, his claims are difficult to refute. Final Fantasy XIII is, put simply, the best looking game on Playstation 3 yet.'
'The characters, all fully motion captured, stand with poise and move with grace, acting the script, not simply reading it out for the cutscenes. Depth-of-field camera effects shift focus on the fly, drawing the eye to layer after layer of minute detail in a kaleidoscopic distance. Lights blink and twinkle in a deep green sky, while pinprick particles swoosh by in the wind of a forgotten hinterland.'
