Sense he has 2 of the starters already. I think he will get the last. As long as no one in his new traveling party gets. But ya. Here is mine. Sorry I have not learned all the names yet. Probably will not till English names.
You got to remember,Ash always has a balanced team. So I am thinking he will get a Steel/Ghost/Dragon or just some other random type.
Pikachu
Last evo of Pokabu
Last evo of Mijumaru
Last evo of Tsutarja
Last evo of Mamepato
Some other pokemon.
Also Iris is the final gym leader or suppose to be so I am thinking she will get all dragon types. Ash may even give her Gible to help train it.
With Jessie and James being better bad guys now. I am not sure what they will get. Jessie will probably realse Wobbfat and get another with Givoni's orders. James,I am not sure. Past seasons he has gotten pokemon from his childhood. So I am not sure.
