@ Mannat,
CIC's role is finished after your sponsorship approval. The File will be transferred to NDVO. PP request can be an email, snail mail or phone call to you. NDVO will contact you regarding your PP not your husband.
Let me tell you another secret. Getting PP request within a week after file transfer doesn't result in quick DM. Many applicants get PP request after two or three months and get their passport back with visa with in a month after that. Whereas the Applicants who got PP request immediately after file transfer, their PP are still stuck in NDVO from the last 4 to 6 month's time. Because every case is Unique.
SO the proper answer for your question "What's Next" is PATIENCE and Only PATIENCE !!!
I hope you can digest this fact.
All the BEST,
GULZAR !!!
