Spoilers [Spoiler] Starter final-evolution type predictions?

Grookey, I think, may end up as a Grass-Fighting Type
Scorbunny will probably be Fire-Normal
And I think Sobble might become a Water-Ground
This is only speculation, as I've only seen fanart of them, and that's just how they strike me.

 

Grookey - Maybe Grass/Fighting? I'm not really sure.

Scorbunny - Most likely Fire/Electric. Might be Fire/Fighting as well, though I don't think a lot of people would be happy about that.

Sobble - The invisibility makes me think Water/Ghost. I have a feeling it could be Water/Poison as well.

 

Grookey- I like the idea of Grass/Fighting like a lot of people have already said. My only issue is that that might make it too similar to Infernape. Grass/Dark might be kind of cool.

Scorbunny- pleasedon'tbefire/fightingpleasedon'tbefire/fightingpleasedon'tbefire/fightingpleasedon'tbefire/fightingpleasedon'tbefire/fightingpleasedon'tbefire/fighting You know, I really like it's white coloring, which I think its kind of an interesting choice. Like an arctic hare. Having a Fire/Ice type would be pretty cool.

Sobble- I'm going to guess pure water type?

Honestly I think all three of these would make good pure grass/fire/water types and I wouldn't be disappointed by that.

 

Grookey - I'm... really not so sure. I think It could remain pure Grass but I feel like they wouldn't do that. Maybe part Fighting, Ground or Rock but its really hard to tell right now.

Scorbunny - I have a terrible sinking feeling we'd be getting another Fire/Fighting Type. It already looks like its on its way there. But then again Litten did end up turning into a Fire/Dark instead of Fire/Fighting so we may be in for a twist here. I'd laugh it turned out to be Fire/Fairy though. I heard Fire/Electric is popular and I'd be totally on board with that. That sounds really neat!

Sobble - Water/Dragon or Water/Poison. Those two just seem the most fitting to me if they dont make the final evo into just a pure water type.

 

Judging by the game being heavily influenced with British themes:

Sobble could go to revolving around the Nessie AKA the Loch Ness Monster seen in the Scottish highlands. Maybe have elements similar to a plesiosaur which was the basis of Lapras. If this is the case, I don't think they'll do a Lapras clone with water/ice. I'm thinking more of water/dragon, water/poison or maybe even water/ghost.

Grookey is really interesting because I'm not even sure where they'll take it. Going back to the British influence; a big speculation I had was the stick it wields that it puts in between its hair and was beating on the rock in its first appearance. It screamed DRUMMER. The British invasion with the huge music groups like the Beatles, Rolling Stones and Dave Clark Five were a big influence at the time. Plus Grookey sounds like Groovy...which was popular UK slang for "cool" and "hip" often associated with those types of music.
It's difficult to pin down what typing it will be. Could just stay standard grass, but I wouldn't be surprised if it went grass/rock.

Scorbunny looks interesting too. (Naming it Chungus ) I know the fans don't want another fire/fighting type and it's always a possibility. Honestly, another fire/fighting type needs to just be available as a wild Pokémon from here on out rather than a starter. It's appearance reminds me a lot of a football (soccer) player, which is obscenely popular in the UK as well as the rest of Europe. Seeing from the trailer that we go into a stadium that resembles a football one, I'm hoping this could be the motif behind its design. Scor has that cool double meaning too with both "scorch" and "score"
Type speculations? Obviously pure fire, but I'd like to see it be something like fire/electric or fire/normal.
