Idk, i obviously hope for the best, but looking at facts it's different. What i mean is that in my opinion we can't expect a remake like the older ones. Firstly, these games have a total different design, while the older ones looked exactly like the generation in which they were released (in this case they should look like swo/shi but we got smol down instead), secondly older remakes had the full Pokedex, and here it's quite sure we will probably have only gen 1 to gen 4 Pokémon, almost like a let's go game, in some way.
Then, the website (the Italian, at least) says that those games will have the exact same story and they highlight how everything was kept equal to the original games. Now, this is something weird because if we add a "giratina event" then the story isn't exactly the same. I think it's quite cryptic but I personally wouldn't exclude a giratina or even an Arceus episode added to the original story. Plus, we don't have the cover yet, which could mean new dialga and Palkia forms, but, again, if it was like that then the story wouldn't be "exactly the same" as they say on the website. Now, realistically, what I expect is that platinum won't be considered except the new Pokemon introduced only in that game, that's why we can see the lady who was only in Pokémon Platinum. I also think that if we have a chance to visit again the distortion world, we shouldn't have high expectations: maybe it's gonna just be the short exploration to get the grigeous orb and nothing more.
