Most of you (Cliffy B. included) don't realize that would have taken weeks to come up with at the very least so I would have to assume they considered this right after the reveal. That means they were heading into E3 knowing this (a major reason why they weren't talking about DRM and blocking used games). The preorders weren't the reason they did this nor was Sony's E3 showing, those were just icing on the cake. The real reason was the backlash right after the Xbox reveal event. Also just because the obvious DRM was removed doesn't mean that DRM is fully removed. All those Xbone games are still relying on "the power of the cloud" so those games will still have some "DRM" in them.
