Check it out, in the pages tab just under the header. I'm really looking forward to this event!
Here is a pic from my fellow DMB member Deke's awesome Exterminatus Megabattle event in 2006. There were several satellite tables as well as a main table. This picture was from a battle over a subterranean mining complex, and the victor's forces could crawl up through the access tunnels (you can see one behind that pillar in the center) to assault their enemies on the main table.
The event was a great success, and is still talked about in awed tones to this day. I'm hoping that folks who play in the Brawl Narrative Apocalypse event will be doing the same!
