>>45953931<<Centro Leaks>> said it was going to be in the classic style, which is exactly how they described the Let's Go games in reference to being ""core mainline titles""
The burden of proof is more on it NOT being a Let's Go style game, since in order to make it like SM/SWSH they would need to completely revamp the maps and arbitrarily gate things off so that the flagpoints on the map can function properly for the purpose of railroading.
Also, I can't see a HGSS/ORAS style remake happening with the dex cut. SWSH and the remakes don't need to be compatible at all with the new policy and if that's the case I see them making it a self-contained remake like the original LGPE that way transfers only become viable for Gen 9.
