> I need the pro version of Unity3d to generate iOS, Android or VR games for the Oculus Rift

Not true anymore. You can generate iOS and Android versions of your game with the free version of Unity3d (although with a reduced featureset in comparison to the pro version).

I think he was referring to the Oculus Rift part. Pro has one feature (is it deferred rendering?) which is requisite for OR development.
