Speculation Will the potential DPP remakes feature Dynamax?

I'm fairly certain Z-moves weren't in LGPE because held items aren't a thing in those games and decoupling them from held items most likely would have been problematic, not because GameFreak thought they'd be too difficult for newcomers to grasp. Megas were probably implemented because they're a flashy and exciting mechanic and because it's the only way Charizard can be part Dragon.

Megas did have a held item requirement too, and they just scrapped it, so held items were probably not a factor in Megas vs Z-Moves for LGPE.
