An interesting weekend? Halo has been previewed again in PC Gaming World, and halo.bungie.org has posted a scan of the article. The first paragraph sets the tone for the whole article:

Not a lot of new information, though. The most noteworthy tidbit is that human air vehicles have been mentioned, which means the Covenant might not have a monopoly on air power.
