purports to say that Halo 2 comes out "for real" in March.

I'd just like to point out that no release date has been announced for Halo 2 by Bungie, and as such, everything else is... well, not official and not "for real". Nobody else is in a position to know but Bungie-- and they don't tell not because they like to toy with us (although they do) but because they don't know because Halo 2 isn't done yet.
