Newcomers Potentially Chosen Based on Improved Capabilities of the Switch 2
One thing I don't see people take into consideration with newcomer predictions is the possibility of characters being chosen based on the improved capabilities of the Switch 2. It's a more powerful console that's been able to run current 9th gen games like Resident Evil Requiem, and games like Donkey Kong Bananza were able to reach their full potential because of this. This could potentially have an impact on which characters are chosen, or at least some of the choices.
One example could be who they choose as the Fortune's Weave rep, which could mostly boil down to Cai or Leda. Cai because of him being a riding unit and riding his giant bird throughout the whole battle, or Leda because of her summoning demonic beasts, which would have these giant creatures active on the battlefield and maybe even controlled by the player.
Another example could be the Howard Twins with their Legions. I wouldn't be surprised if they were like Rex & Pyra, where the legions with the twins couldn't be handled in Ultimate due to the weaker power, but with the Switch 2 they could use the Legions to their full potential.
Speaking of Rex & Pyra, maybe this is when we actually get the Driver and Blade mechanic due to the increased capabilities, since this was what the Smash team was originally going for with a Xenoblade 2 rep.
What are some other characters you think could get added or would simply be able to take better advantage of their toolkits because of the Switch 2's increased capabilities.
