Everyone knows Halo is good because of Bungie, not because of Halo. It is therefore likely that while Halo 4 might sell ok, the next Bungie game will demolish it. So why even bother? Just have Bungie make Halo4. I could see Gearbox making some kind of spinoff like those terrible Call of Duty spinoffs though. Has Gearbox ever made *ANYTHING* good?

In summary, Bungie forever!
