hmmm i am not sure we re gonna see new dialga and palkia forms and that's one of the reasons y i won't buy the game. that would be disappointing anyway if they made new forms of dialga and palkia just giving them their orbs, because nothing happened in the past. why would they change their form only now? lol
also, a powered from or an original for of dialga and palkia kinda doesn't make any sense at all because those are the original forms of dialga and palkia already. and they can't get stronger, if not implying the whole multiverse story, but these remakes won't have a different story, so it's just useless.
the only good thing they could do is introducing alternative forms of dialga and palkia when they enter their own dimensional worlds, but when it comes to lore these have some problems as well. Like, why would they change form? are they like giratina? but giratina was banished by Arceus to the distortion world, does this imply they were banished as well? why? and so on...
so idk. to me it's kinda probable we re not gonna see any new forms
