Keen eyes have spotted this careless passage published in the PlayStation 3 version of the NBA 2K7 instruction booklet: "Once you start feeling your heart rate pumping (via controller vibration), you'll be ready to begin! Shooting free throws in 24/7: NEXT is just like shooting free throws in a normal quick game" (page 15). The rumble citation is an amusing relic of pre-Sixaxis days when the manual's authors must have assumed (or were told) the final PS3 controller would feature a standard vibration function. Guess 2K Games didn't bother to hire a knowledgeable copy editor.
Please, let's not assume this means PS3 games have 'hidden' vibration features. A typo's a typo. And PS3 launch titles won't be a'rumblin.
