Not Yet
My wife's rollover has still not posted, though her 2015 Amex spend has been updated a couple of times already.
If it posts now, she will show rollover above 25K. However, this will change later because after her statement closes, probably today, she will get her 2nd 15K boost. Since it won't post automatically, I assume her rollover won't change until she collects the 15K miles putting her back to gold for this year.
Her next flight is 2/4 so there's time to get her back to gold.
