Are you familiar with how the service center fix is done? Based on comments I have read from those who have had the fix done, the re-flash is at a level not accessible through the running firmware. It is unlikely that a firmware update will totally cure an effected camera without a service visit.
That being said, it is highly unlikely that the flaw is present in current K-3 production. That is the way these things work. A good example would be the sensor stains on the K-5. Those were quite common and Pentax fixed a lot of cameras, but was completely absent from later production.
I would suggest that you have done your research and are in the position to make a decision. Given your ambivalence, I would suggest a Nikon D7100 or Canon 7D Mk II instead.
