I think people expecting more than 100 were a bit...lofty in their expectations.
I'm still thinking it will be the 84 island scan pokemon formally added to the dex (I mean...you can capture them just fine during hte main adventure. little silly!)+ the 2 new UBs (who in the alola dex i assume will come before necorzma and not after) + a smattering of other pokemon
If we assume Mantine's line, remoraid's line by extension, and Meinfoo's line are all in that'd leave 8 spaces.
If the island scan pokemon are added to the wild encounter tables instead of staying island scans, I could see the gen 2 & 5 starters swapped out for other pokemon, though, so that'd give another 18. Also if they are removed from Island scan, I can see all the pokemon being replaced with another 28 families.
