If the Tyranids have any true weakness, it's that they, like parasites that kill their hosts, are a little too successful at what they do, leaving them without a food source. Sorcerer Du'un was absolutely spot on when he said that the 'nids are simply running from starvation.

Back to the convo at hand though: Lord of Silence makes a great point- Technically, if there were a large enough population of any psychically sensitive, sentient creatures anywhere in the universe, then a whole new set of 'Chaos Gods' could theoretically be born. Unless something the Old Ones specifically did to alter the Immaterium directly created the Chaos Gods? I'm not sure that's ever been solidly confirmed one way or the other...
