Sure, these pics are horrible, but the Reach weapons and enviroments are still noticably better than in Halo 3. The vehicles may not look as good, with the exception of the ghost, but it's because they don't have as much wear-and-tear on them yet (heck, the covenant JUST attacked Reach, it's not like brand new warthogs are gonna come with laser burns straight out of the factory). Bungie's just trying to match the weapons and vehicles to their appropriate time placement. Personally, I though that the Mongoose was better looking in Reach, only because it was more diversified.
