I'm way too uncool to even know what that means, but that's how Frankie described Halo 3 in an interview with Eurogamer.

On a more intelligible note, he also said:

Well, we haven't lost a single [new] weapon thus far, but we've improved a few. Our test process is simple. Play it, play it some more, take notes, make changes, play it more.

The question was about the process for coming up with new weapons; so I assume it means that none of the new weapons envisioned for Halo 3 have yet been eliminated, although some may interpret it to mean that all the old standbys are also back.
