  Evidence for a spectral line in the inner Galaxy has caused a great deal of
excitement over the last year, mainly because of its interpretation as a
possible dark matter signal. The observation has raised important questions
about statistics and suspicions about systematics, especially in photons from
the Earth limb. With enough additional data, we can address these concerns. In
this white paper, we summarize the current observational situation and project
future sensitivities, finding that the status quo is dangerously close to
leaving the issue unresolved until 2015. We advocate a change in survey
strategy that more than doubles the data rate in the inner Galaxy, and is
relatively non-disruptive to other survey science. This strategy will clearly
separate the null hypothesis from the line signal hypothesis and provide ample
limb data for systematics checks by the end of 2014. The standard survey mode
may not.
