— As the leader of Pelargir, Kemen will be given one of the nine and will eventually become the Witch-King

I agree with you here. Seems the obvious choice from the beginning. I question who the other two Númenoreans will be.

— Theo will eventually become leader of Pelargir after Kemen is run off by the Ents. He becomes the King of the Dead.

Seems an obvious choice as well

— I'm torn between whether the Dark Wizard is Saruman (which doesn't make any sense but seems hinted at) or one of the Blues. Especially now that we know the Stranger is Gandalf.

The showrunners put a lot of doubt into this one as they said who most people think it is, it is not. I’m guessing it is one of the blue wizards

— Nori and Poppy will lead the Harfoots and the Stoors west. The Stoors settle along the Great River and are Gollum's ancestors. Nori leads the Harfoots to found the Shire.

Wow, I really hope they devote the time they’ve been giving to the Harfoots to Númenor instead. Númenor needs more screen time, and the Harfoots plot is pretty boring. I hope we don’t go on the journey with them to settle their lands.
