Update- I applied for the account on 10/13 and I just found out it got approved yesterday. I had called them on Friday to ask about the status.
At the same time, I had applied for an account for my wife, but it has not been approved yet. I think it got moved to the front of the line because I called, possibly.
They did however mention that they are working through the backlog of applications they have due to the promotion, and I would still be eligible for the promotion even if they don't get the application approved before the 15th.
