My guess is that the expense of the repair program does make it a priority, but that they didn't have enough time between admitting he problem and releasing this round of machines to come up with a new design that both fixes the problem and is low-profile enough to fit in the space allocated. It's only been a few weeks, and they may have already begun manufacture on these (let alone design) at that time. I would guess that the next spec bump will include a fixed keyboard.
