do we have a date yet?

Nope. If it is the 10th, we probably won't get an announcement till next Monday at the earliest. 

If it is the 10th but they announce it today or tomorrow, then it's a BIG one.

Expecting:

• Pokemon
• Xenoblade
• Ocarina of Time
• Just Dance
• Zelda Movie Trailer
• 3rd party reel
• Some big 3rd party announcement
• New announcement of a Kirby game (last mainline title came out in 2022, normally they release one mainline title every 3-4 years, so it's about time!)
• Mario Kart World expansion DLC
• Something about their amusement parks

Hoping:

• Wii & WiiWare NSO
• Sega Master System & Game Gear NSO
• PC Engine/TurbographX NSO
• Sega Saturn NSO
• Dreamcast NSO
• Neo Geo NSO
• Sharp X68000 NSO
• Some more games for the GameCube NSO (looking at you, Gladius!)
• Come on Bowser, give us Mother 3!
• New F-Zero
• New Paper Mario

Nintendo's pretty consistent saving Paper Mario for every four years (if we're counting TTYD Remake in 2024). I'd say give it another year/year-and-a-half before we see anything. Crazy to think though that it's been six years since Origami King released! Biggest gap between mainline entries in franchise history. Really looking forward to seeing what IS is cooking up especially now that the original director has (mostly) retired from his role, and the heir (who oversaw the TTYD Remake IIRC) will be in-charge.

The dates speculated are the 8th and the 10th with one claim that a double ND will take place, a partner direct being one.
