They're not quite ready to be thrown on the cart yet. David at Halo Central clears things up:

Halo Central would like to report that rumours of our deaths have been greatly exagerated. After a wee bout of the bubonic plague we're back at it. By it of course, I mean the news game. That's right, so pop on over to Halo Central again where we're back on track and ready to rock with all the news of the Halo world.

Nasty stuff, that bubonic plague...
