Diamond and pearl remakes.
They’re still in development, so some things might change (slightly). The announcement was going to be soon (but coronavirus might have delayed that) I don’t know any date.

>Will be called “Time Diamond” and “Space Pearl”
Yeah, I know, suuuuper lame names, but it is what it is.

>No megas, but Dmax and Gmax are in the game
Not really a canon explanation, they’re like “oh, this is a thing now”. Like how megas were in Hoenn.

>Gmax
Spiritomb (out of the stone, kinda its “true form”)
Lucario (think of an armored Lucario)
Chimecho (same style as gmax centiskorch, reeeeeally long)
Rapidash (the fire comes out of its back, like wings)
Vespiqueen (the hive is the biggest part, combees go in and out of it)
Hippowdown (bigger back piece and sand “waterfalls” coming out of every hole.
Garchomp (stands on four, and it’s chubbier. Real look of a shark
Alakazam (it’s like glowing from the inside, I don’t know how to describe it. Attacks with the spoons)
Luxray. Looks more like a panter. I think this is the coolest one.
Abomasnow. Shape like a Christmas tree.
Bronzong. Doesn’t change that much (that I noticed), it’s upside down
Floatzel. The floater is more in the belly now. Gives the impression of an aquatic themed park. I don’t know. Weird
Most Gen8 Gmax will be avalaible too
