I already post these in my blog post, but here's the abridged version:
*Eldegoss's incredibly low weight suggests it will evolve further, since final evolutions tend to get a massive weight boost, in allusion to insect fighting(better insect is the heavier one).
*Despite its model, Drednaw is heavy as Rhyhorn, who is heavy as a lot of fully evolved Pokémon, and it is large as Basculin. Since we also saw it face-off against Gigalith, it is more than likely a standalone, but Mudbray has similar weight/height, so it might get a very large evolution.
*Corviknight is large as Mega Pidgeot, which follows in the line with the theory that it is based on the black blob bird that appears in HM Fly's usage. Since it is as heavy as Crobat and Quagsire, its BST is probably high, around 485 if it is standalone, 495 if it is two staged, and 505 if it is three stage(even if it is not the early bird, it is still an early bird so it won't get much high BST). Either way, unless Skarmory gets the same 485 BST as Gen 7 Mantine, Corviknight will be stronger, just less competitively viable.
*Wooloo is roughly the same height as Deerling and Skiddo, but much lighter, which suggest it will evolve once, but most likely only once due its height. Probably will get another type due to its primary Ability(Fluffy) and its secondary Ability(Run Away) which will almost certainly be replaced in evolution, since there hasn't been a fully-evolved Pokémon with Run Away since Gen 5's HA Pachirisu. And no, Run Away will not get buffed significantly(they would've shown us if that was the case).
