It's very unlikely but they might evolve Ash's Pikachu.
Why? They're giving Go his own Pikachu. Since Pikachu is the biggest symbol of the series, they are transferring the protagonist badge to Go. Sort of like how a scepter and crown was the symbol of kingship and was passed down to the next in line.
