Well, Kotaku has picked up the story, and Brian is now saying that he doesn't remember the controller rumbling when he used it at Leipzig. The loss of rumble would certainly be an odd switch, but it could be that they didn't want to pay Immersion for the licensing.
In fact, now the rumor of DVD playback being nixed leads me to believe that Nintendo is trying to aggressively cut costs, since the license for DVD playback is an easily avoided fixed cost. Still, the business person in me keeps saying that since the DVD playback would have only been possible through an add-on, you could pass on the cost that way, but there must have been another cost component.
Still, unlike DVD playback, rumble is still featured in the marketing materials. Also considering that there was a time when both were present, I wonder when this decision was made.
