Compare what we know about Sword and Shield right now to around this time when Sun and Moon was about to come out. It's a lot less. We know around a dozen new Pokemon, four new forms and like 6 characters. Most of the news has been on the "Pokemon but bigger" mechanic and how Meowth is suddenly Inugami and Pikachu is fat again and whatever, but that's... really it.
Not saying that's a bad thing. Keeping a lot under wraps so people can react when they find it is nice, though it does slightly concerned about how there's suddenly no information to share when, for the last two gens, we got basically everything short of the plot shown before released.
Also, most of the new things are Gen 1. Insert generic "omg gen 1 sux lolololol" comment here. Though in all seriousness, does Charizard really need a new form? You can tell who the Pokemon Companies favourite child is. " You can have 2 new megas, a new giant form that makes you look like Godzilla with fire wings and we'll ditch the other lame Gen 1 starters so you can be the star of the show in Smash 4". OK. Done
