It's understandable for one engineer to overlook it, maybe even a whole team but for an entire division of design, engineering, QA, marketing etc? Something is rotten in their process.
QA should have had a short window to study this type of issue but is it something that they would delay shipment over?
Basically I would expect the product to ship on schedule unless there was a really critical problem and that there wouldn't be slack in the schedule for weeks of refinement. Component orders may be place 6 months ahead to secure supply so it is hard to flex the schedule without causing inventory problems not to mention messing customers about.
Based on my experience in a CE company that wasn't Microsoft.
I would assume MS is not shipping products directly from the engineering lab to the factory, so for something glaring to get all the way to the customer then there is something wrong in their process that failed to correct for human error.
They are not supposed to be worse?
