Here's something that should make even the Steve/Alex-haters happy:
Outside of maybe an eighth-generation Pokémon, Steve/Alex was the most "obvious" FP2 character. Like, Minecraft was by far the biggest "missing piece" in the Smash universe, and now that piece is filled. And there's still four more characters! And now that one of the most obvious picks is out of the way, we don't know who those characters are going to be.
It feels like we're in uncharted territory, now. The biggest "sure bet" character got in. What's left? Even if we assume the most "obvious"/boring characters get in, and one is an eighth-generation Pokémon and one is a Monster Hunter, there's still two more "left field" characters left to wonder about.
