It's so early and minimal an announcement, I only am feeling expecting for more info than having an opinion on it.
SwSh was ok, a step back from Sun and Moon overall, better than XY. I'm somewhat disappointed in another Euro region, probably cause two of the weakest Gens we're Galar-England and Kalos-France. Would of liked a South America, Steppe, or Middle Eastern region adapted. Surprised the region isn't named.
On the starters, I think I like Fire the most, it's round doughy nature reminds me of Gen 1. The ducks ok, appears to bea sailor. Whoever called the Grass a Neopet it's spot on. However, starters first forms are rarely indicative of their final form. Froakie and Sobble both start out longer shit, and end up decent. Gen 2 and 5 are good games with no good starter pick.
I'm most curious what they gimmick will be. Mega Evolutions were ok, but I don't miss them, Ultra Beasts we're dumb, but regional forms were fantastic and are now a staple, Dyna/Gigantomax were just worse Mega Evolutions.
