To be fair, color mine as somewhat unpopular opinion but... do we "really" need more informations on the game already?
Don't get me wrong, I myself am still curious on a few parts (like, which/if regional forms will happen, non rumour-from legendary types and abilities, the region name, what/if the super mechanic is, etc), but it's all things we'll get to know eventually, and to echo on
Lightchao42 there's also a decent chunk of new games releasing anyway right now to catch my attention (rip my wallet QQ).
Pokemon games are at a point where they don't "really" need spam of advertising to hype the audience anyway, and with how many terrifying PR failures they've made in the last years, honestly the less they do the better.
I may also be somewhat biased because another company I stan for has this awful habit of spamming trailers for the games they release almost every day (*sighs at Atlus*) to the point where I stop following their yt channel because it just becomes boring to know 90% of the creatures present in game as well as 90% of the main cast before it even releases.
