Speculation All Ash's Alolan Pokémon at Prof. Kukui's home to return in the new anime series?

[Thomas Wiencek]

What's happening with you guys? I'm just wanting to know whether or not you think that all Ash's Alolan Pokémon that he had left at Professor Kukui's home will return in the new series of the Pokémon main TV anime? Why? However, Rowlet, Litten, Meltan was shown on the poster for that series, it is unknown whether or not they're Ash's Rowlet or the other. And it is also unknown whether or not they're Ash's replacement Litten and Meltan for his Incineroar and Melmetal, or the others. Please let me know, thanks.
