No one knows, it hasn't even entered beta yet so its going to be months not days or weeks.
If it entered beta tomorrow you could be looking at 6 weeks i guess but it all seems very quiet doesn't it :-(
Both 8.0 and 8.1 were available as a beta before the stable versions were launched.

Hi, the Android Pie is currently available for the Nokia 3, 5, 6 and 8, roll-out will be phased as usual to secure quality delivery.

OK so I don't think this is the case . Currently Nokia 7 Plus is the beta with Pie and we will have more news shortly on 7 Plus and other products
They clearly meant Oreo, not Pie.
Read the answer from Juho Sarvikas, he is chief product officer at HMD, I'd say he knows what he is talking about.
