Too little memory in the PS3. That split 512MB of RAM (256MB for the CPU and 256MB for the GPU) effectively forces Bethesda to try and make Skyrim work with just 256MB of memory and it just isn't enough. I don't think the PS3 is going to get any Skyrim DLC and it isn't worth the cost/time to redesign, reimplment, and retest their game engine specifically for the PS3's memory layout, especially since new consoles are expected next year. Huge mistake on Sony's part to skimp on memory.
