  The new MEG bound on BR(\mu\to e\gamma) provides the strongest upper bound on
the scale of gauge mediation of supersymmetry breaking. If, in the future, this
decay is observed by MEG, the mediation scale will become known to within one
order of magnitude, and the seesaw scale will be constrained. In such a case,
contributions from Planck mediated supersymmetry breaking are likely to be
non-negligible, and an interpretation in terms of purely seesaw parameters will
be impossible. The recent evidence for |U_{e3}|~0.15 further sharpens the
predictions of gauge mediated supersymmetry breaking.
