ARMAGEDDON ADELAIDE March 5th and 6th

I seen this advertised at my local Adelaide Comic Centre and the shop was busy so I didn't hang around to get any info.
This is the first time Adelaide has hosted one of these, usually been the eastern states.
Has any oz member been along to one? Are they anything like a comicon?
Are there collectables on sale? Are they worth checking out?
Any info about them would be greatly appreciated, cheers.

I've been to Armageddon for a couple of years in Melbourne. I'll go to see the speakers but will normally buy something too.

I'm going to the Sydney one, the first (proper) one there ever. They're doing it Supanova style, in Homebush. A fair few interesting things planned so I'm keen.
