At this point, not a bone in my body thinks that SI deals is anything of that nature.
That being said, I would completely endorse and buy HELLJUMPERS, a third-person squad-based tactical shooter set during the Human-Covenant War. Particularly if it has visuals and a gameplay framework similar GRAW, the cover mechanics and fluidity of movement from GOW and the general, frenetically close-quarters vibe (ironically) presented in the Halo Wars' computer-generated trailers.
A squad of four ODST being sent into Reach, for example, on specific and incredibly significant missions which support the Spartans and the UNSC fleet would be spectacular. Rather than focus on vehicle warfare and large-scale battles, which were Halo's niche, this game could focus largely on up-close and infantry-centric combat involving the personalities and lives of these four elite ODSTs as they battle against Covenant SpecOps. It also would show the Spartans in a completely different light as well... cyborg giants which have generated some level of hatred and scorn from the ODSTs.
It would be a completely different take than Halo, commercially acceptable and incredibly bad ass enough for anyone who like shooters to be on board. So yeah, it's got my vote.
