Hi there, new year, same routine. It's not your usual italian localization dude and I'm here to drop some infos on the DP remakes. For starters tho, I've seen a lot of BS about "Sword/Shield 2", it will never happen, while SwSh project had to be rushed, GameFreak has no plans to revise anything about Galar and even by a profit standpoint they think it would be a very bad move. Moving on to the actual info:

>As many have guessed, Sinnoh forms are going to be a thing, this is a standard GF will use in every game from Gen 7 onwards. Most of them are obviously Gen 1.
>The game has no Platinum improvements much like ORAS had no Emerald stuff, except the regional Pokédex will be expanded.
>Hence Battle Tower only, much like Sword and Shield one it will be useful for competitive aspects.
>After the main storyline you'll unlock an expanded pokédex with 600 creatures, 430 of which are the ones you can already catch/transfer in Galar.
>Dialga and Palkia are going to be actual Primals, the Adamant Orb and Lustrous Orb are going to work like Red and Blue orbs
>Aside from unlocking the smaller island in the post-game, there will be a bonus Episode (much like Delta one) where Team Galactic leftovers are going to summon Giratina, you are told the legend of Arceus and go to catch it in order to tame Giratina and catch it too. They both have a new form.
>Dynamax is not going away. The tale of the giants written on the plates (Since Gen 4 games) are now linked to Eternatus and giant Pokémon.
