Pokemon: Goh gets a Pikachu. What could possibly means for Ash's Pikachu?

A recent detail for an upcoming episode of the brand new Pokemon series confirms Goh getting his own Pikachu after looking at Ash's. Apparently all the Pikachu were digging up Thunderstones from a rocky area,trying to evolve into Raichu. However,Ash's Pikachu also shines a light of evolution. So.. What does THAT even mean for the future of the Pokemon series? Let's discuss,shall we?

Ash's Pikachu finally evolves.. (Just a theory. We know how the Pokemon Company likes to trolls.)
Ok so Ash's Pikachu might possibly evolve in the series. This could be a big change for the pokemon anime. In case you don't know,Pikachu is the main mascot of the Pokemon anime. Back in the original series,Ash's Pikachu refused to evolve. However,we do know there are big changes coming for the anime very soon. Could Pikachu's evolution might be one of the reasons? I don't know. Imagine Ash with a Raichu. That would be so much fun. And Raichu keeping Pikachu's personality upon evolving? With pleasure!

Gigantamax (Ok,just a theory)
Like I stated earlier,the Pokemon Company likes to troll us pokemon fans. What if Pikachu don't evolve but instead turns into his Gigantamax form,like what happened in the Leon episode? That may explain something,right? If it does turns out to be Gigantamax Pikachu,that would make it the second time it makes an appearance in the anime.

Goh's Pikachu could replace Ash's Pikachu
You may say it's a dumb assumption but hey,anything is possible now. I think this could be a more possible way to change the pokemon anime. There is a theory going around that the new series is a warm up to Ash's last journey before replacing him forever. Well if you look at Goh,he does looks like an Ash wannabe. He does have Ash's personality. And the fact they gave Sobble to Goh might just be one step to not only develop Goh,but to prepare us for the future. Now look at that. Goh is getting his own Pikachu. Ash did start with Pikachu as his partner. And to think they're giving Goh a Pikachu? Yes,you get the idea. If Ash's Pikachu does evolve,then Goh's Pikachu could replace the former Pikachu. So in my opinion,Goh will replace Ash in the future.
