Good point. Totally hadn't considered that. If it is an Incisor (not some model reuse or something), even a prototype model, that would also seem to rule out the First Contact War theory. I'm still betting that, if it is indeed an ME-related thing, it's something along the lines of a Halo 3: ODST type spinoff where you're involved with events that take place during, and on the periphery of, the events of ME or ME2 (or 3).
