I personally feel like unlike what a lot of people feel, I don't entirely feel 100% confident that SwSh is somehow going to dominate Nintendo's floor or anything. While it's possible it might have a pretty sizeable timeslot, I do wonder whether or not it'd be better off for Game Freak/TPCi to have their own little Nintendo Treehouse showcase thing post-E3. At least this way, Nintendo is still able to showcase the games by giving it some attention, but not without compromising on showcasing their other first-party titles as well as indie titles which is something they've been pretty gung-ho on pushing.
As for the actual news, good on Game Freak for keeping character customization, although one would think they'd be crazy to omit the highly beloved feature altogether.
