Okay so here is the presents roughly:
Pokemon day guy pops on after a special short 1000 pokemon video different from the previous one.

Talks about spinoffs
New PMD game with all pokemon up to gen 9, not a remake.
Cafe Remix and Masters EX news
Unite Zacian Event announced with a few additional pokemon teased one of which wasn't datamined

First three gens are on the online and home compatible, with events included. (Yes you can shiny hunt mew in emerald.)

Home support releases after the presents for SV

DLC 1 and 2 announced

Mostly DLC one stuff that was shown, but a few dlc 2 things can be seen in the overview, being a Zygarde following the player, and another player in a battle with mawile mega evolving and a groudon becoming primal right after. Some new paradoxes were quickly shown, like a metal kommo-o and a rock metagross. You also see a quick glimpse at the leaked Paradoxes too, being the psychic/fighting paradox sword and the fire/water paradox beast that khu leaked.
At the end of the trailer a lizard with crystal eyes is shown that gleam.
Then an overview is done over all the stuff they showed and release dates are given.

Presents ends.

Have fun
