  We comment on recent results of a possible finite theory of Super Gravity
from both Feynman graph and global E(7,7) symmetry arguments. The four point
amplitude can be written as a series in the gravitational coupling and energy
squared, Gs, multiplied by coefficient functions of the scattering angle. Every
order of the perturbation expansion violates the unitarity bound for any
element of the S matrix by powers for large values of the energy. While this
conclusion is not unexpected; the meaning of such a theory is not understood.
Either the theory is not finite or a non-perturbative completion is necessary.
We first review the semi-classical eikonal methods, and then examine Borel
techniques to sum the series. Although many details are unknown, we present an
example of how an asymptotic behavior that is power bounded and consistent with
unitarity might emerge.
