All you need to know is that Generation 10 will indeed be based on australia
Part of the region will branch into new zealand as well which is why the grass starter is based on their native kiwi bird
Really cool thing about the platypus starter being part poison type is that it references them sweating toxins as you may have seen in a phineas and ferb episode
In other fun facts, yes, the fire scorpion starter will be the first pokemon to look like a bug while not being the bug type
Lastly for starters, the kiwi being a flightless bird means that it won't get the flying type

Furthermore, scarlet and violet will not be adding back megas
Oh, but the terramax forms are indeed coming which is the same ideas as megas and gigantamaxes
One more thing before I go, you get all 3 of the munkidori, okidogi and fezandipiti trio, you won't have to choose
Leaving now
See you
