Predictions:
Fatalities in the 1000 range.
Superdome structure intact, few if any fatalities inside from unrest/panic/stress. Stories from dome are mostly uplifting tales of survival, faith, prayer, and song.
Some areas of NO never rebuilt. (But the tourist areas will live again).
Oil released from strategic reserves to reduce price spikes.
The cost dwarfs that of Andrew.

That's my guess on the lower limits. I don't expect any civil unrest at all. People tend to pull together in a time of crisis.

Don't ask me about my high side guess.
