My predictions, hopefully I get some right:
Minute 1-5: Showcase of Pokemon Day Concert
Minute 5-7: New jumbo plush that everyone will want but too bad because the Pokemon Center site will crash 0.5 seconds before release. Don't worry though, because in that time scalpers will have bought everything anyway!
Minute 7-10: Pokemon Go expansion teaser, very vague
Minute 10-15: Teaser of latest new Pokemon TCG archetype: Pokemon EGXVMAX-AF, which have between 500-690 Hp as a basic but do very little damage, in response to player demand for longer, more meaningful games. To balance this, all cards enabling alternate win conditions (Mill, also Mill) will be banned to ensure players enjoy a tense game, and skillful new Hammer cards with no drawbacks will be released to ensure fun. As such, players can now enjoy games which are guaranteed to go into time with no prizes taken so that games are more likely to end in draws so no one loses, ensuring all decks will be competitively viable, which will increase player engagement rates.
Also ADP is being reprinted as a non-A card, ensuring players access to the most fun card ever created. Thank you.
Minute 15-20: Very important presentation by TPC, possibly goes a bit like this...
"Here at TPC we have listened extensively to player feedback. We have listened intently to requests to improve graphics, restore the National Pokedex as well as lengthen our games with meaningful, enriching content. We are happy to announce that we have prepared something to satisfy past and present fans alike while creating an experience to surpass any other that you may have seen in a video game. Here are examples of what we have for you."
Insert 1-2 minutes of screenshots of barely legible quality with painfully loud music in the background
"Thank you. Now, we have heard the popular response for remakes of Pokemon Diamond and Pearl. I'm sure you saw this presentation and expected new information."
"Unfortunately, we don't have anything to share right now. We apologize."
