But remember that the subject of your image will not be magnified as much when using the lens on a full-frame camera. If you consider it in terms of the maximum magnification of the usual view (i.e. normal vision, or when using a standard lens on the camera), the 400 mm lens would give you about 13x on the 650D, but only about 8x on a full-frame camera.
The lens advantages of full-frame sensors work in the opposite direction - an even more wide angle effect from short focal length lenses - to benefit subjects such as landscape and internal/external architectural shots. Their other main advantage is lower noise at high ISO values - useful if a lot of work is in very low light (although even then, modern APS-C cameras can produce good results up to ISO 3200+).
If your main interest is wildlife, whether from a distance or in macro shots, the magnification advantages of an APS-C sensor camera would seem to suggest that your upgrade path (if the 650D is not up to the job) should be a better APS-C body rather than full-frame.
Just my opinions, of course.
Cheers.
