MEM Refferal to ND-PEB National Guard

I have until today had a P3 profile for scoliosis with a MEB referral. The Sate case manager informed me today that it would instead be transferred to a ND-PEB due to my condition existing prior to service which I am ok with. They have said that they will push the profile change up and I should receive a Notification of Medical Disqualification memo within the next month. Does anybody know of any timelines on this?
