Pretty much all of those yup, and the Magic team does Tumbler, too. It wasn't clear till the past few days that this would be as much a D&D event as a Magic event, though.
If D&D is getting equal billing, it might help to compare it what what kind of MtG news we will be getting.
For MtG we will be getting or likely getting:
1. News and a spoiler on Dominaria United & Brothers War
2. An announcement for what the next 4 Standard sets a few details each
3. Some news on Unfinity, JumpStart 2022, and Warhammer 40k Commander Decks/Secret Lairs
4. The announcements and news on Lord of The Rings set and other 2023 supplemental sets (most likely jncluding another D&D set, using the MtG art for Acererak hints at this)
5. A news update on the Netflix MtG cartoon if only to sooth fears its been cancelled along with much of the rest of Netflixes animation department.
6. MtG video game news
So expect something on this scale for D&D.
That could include news on D&D movies and TV (not just Honor Among Thieves), D&D video games (BG3 is getting full release this year), book announcements, details on Dragonlance, Planescape getting announce (the classic setting), a Dominaria setting book to celebrate MtG's 30the anniversary, 5.5e playtest, and the two new setting books for 2023.
And I think the Tarrasque reference most directly relates to one of the new settjngs they've been teasing for years now, The First World, D&Ds new primal setting from the ancient past before all other material plane settings, before even the Dawn War. Tasha's, Fizban's, etc...,
