Said that ADS (again don't know if it's just cosmetic or something) was a big focus in development, now says it may just be limited to a few weapons, but that it'd be a strange thing to focus heavily on if it's limited. Assault rifle does have it though. He also reiterated that all the negative reaction might change things, Microsoft's playing it very safe and there's still 'plenty of time'.
This is precisely what I posted earlier in this thread. I said with the XB1 lagging behind the PS4, that Microsoft could not afford to screw up Halo or alienate its community in any way. If the majority of beta players communicated their displeasure with ADS and Sprint, those mechanics would be removed. People ignored me or said I was nuts to think negative beta feedback would have an impact. :/
