Halo 3 is detail-limited by lighting.

: Just on a point of accuracy, did you have some justification for your
: statement and the one about the Banshee model being exponentially more
: complex? Did Bungie say something?
Bungie has made a huge deal out of the vastly greater level of detail in Reach as compared with Halo 3.
Halo 3 is so detail-limited largely because of its extremely ambitious lighting system. Most of the time, when developers want high dynamic range lighting, they use a framebuffer with high colour depth. Halo 3 aims for a more robust solution, one which is similar to how HDR photography is done in real life: it uses a dual-framebuffer approach, where it's actually rendering each frame at two lighting levels and then combines the result. The HDR quality is pretty much the best we'll ever see on the 360, but there were absolutely massive compromises.
The main compromise that people tend to point out is the low resolution. Framebuffers for 360 games are typically stored and processed in a high-speed 10MB EDRAM pool hooked up to the GPU. 10MB is fine for a single framebuffer, but if you're processing two frames at once, that 10MB pool starts to look pretty small! To fit the framebuffers into the EDRAM, Bungie had to render at only 1152x640.
Beyond that, some things like lighting calculations that would typically be carried out once per frame render in a game, had to be done twice in Halo 3 for the two light levels. So a Halo 3 polygon is typically MUCH more expensive to render than a Reach polygon.
