That's a pretty big exaggeration. I'd be inclined to agree if every character in the game got the same treatment as the main characters did. From a technical standpoint, random NPCs in FF13-2 have more polys and higher res textures than the main cast of FFX. FFX also lacks a lot of effects that you see in almost any "real" PS3 game, such as DoF, HDR and environmental reflections. The game world has a prettier design than most other PS3 games, though.
