Will the game have in game tutorial for new players?
Every Pokemon game has lots of early "teaching the ropes" mechanics. Trouble is, GF haven't got the first clue about how to design proper difficulty scales and don't give a rat's arse about their older playerbase so the tutorials aren't optional, their baked into the game so you will have to sit through them. Every. Single. Fricking. Playthrough.
Even worse, they sometimes have a dude / dudette who offers to teach you stuff, like how to catch Pokemon, and they do it even if you say you don't want it (they say "do you know how to catch Pokemon?" and give you a choice). GF are many things, but competent designers when it comes to challenging a very wide playerbase isn't one of them, sadly.
As much as I'm looking forward to Let's Go, Masuda is totally losing the plot in my eyes and seems trapped in a weird land where anyone who has played GO can't grasp even the most simple concepts without extreme handholding.
