Orks will not win this war. Tyranids will never become "Orky" as the Norn Queens filter out unwanted genes. They have also got all the upgrades from the Orks they wanted, such as the Biovore and other adaptations that I cannot name off the top of my head right now. So the theory of Tyranorks just flew right out the window.

Chaos doesnt stand a chance in Hell (literally) as the shadow in the warp neutralizes them completely.

Necrons are a close victory, as Tyranids are able to consume metals, therefore the Necrons provide biomass and feed the Tyranids. This is backed up by the fact that you never see or hear about any surface metal left on a planet consumed by Tyranids.
