But don't forget that if the races combine, we would have their combined knowledge and weapons that the tyranids can never hope to defeat. The necrons are widely regarded as the masters of the material realm, with all their extreme technology and such. The C'tan, in the form of shards, are still a force to be reckoned with as they are the former gods of the material realm. The eldar also have immense mastery of the warp too. As such, I don't think the tyranids can ever win against their combined powers.
