Computer Games Online has posted up Part One of its newest Halo preview. It includes a number of new screen shots and is very positive in its description of Halo while currently choosing to not discuss the questionable future of a Mac/PC release. Good read - I suggest you go take a look. I think that the fact that they're doing the preview in more than one part suggests that CGO is VERY impressed with Halo.
Additionally, the current issue of Computer Games Magazine (the Dead-tree side of CGO's operations) sports Halo on the cover and has an offer to preorder Halo or Oni for $19.95 from Chips & Bits. Not a bad deal, and definitely worth the $7 purchase price.
