The textures look fine for the most part in most of the levels, of which there's several, either way any important area within the level has perfect texturing. If I glitched into phogoth's chambers I'm sure no enemies would spawn either, that doesn't really mean the level isn't finished. Terminus looks just like the trailer, which would only really show off finished content right? I mean you don't put a half textured area in your release trailers. And just because kill barriers aren't set up again that doesn't mean it's not finished. Outside of that when has XBL or PSN crashed from too many people trying to download a DLC? Seems a pretty shitty justification, it's not like downloading the DLC would make things more problematic for Bungie.
