The only reason there might not be a Gen 10 announcement in the Pokemon Presents livestream is there has never been a brand new generation game released on a new system that was released less than a year earlier. The closest we've gotten to this happening was Gold/Silver (11/21/1999 in Japan) releasing on the Game Boy Color (Japan release date of 10/21/1998). The Game Boy Color was barely over a year old when Gold/Silver was released on the system.

Game Freak so far has never released a brand new generation game on a system that's been out for less than a year. They would have to break with tradition here if we are to get a confirmed Gen 10 release date that is less than one year after the Switch 2's launch (though that system has confirmed release date either).

A Gen 10 teaser can still be possible without giving us an exact release date, but with something vague like "2026".
