Pokémon 20th anniversary

The commercial for it dosnenr even hint at it being Pokemon until near the end it's just really kind of a bad commercial

 

I really enjoyed the commercial, and I understand they don't want to spoil things, but they should've at least showed who the starters are gonna be.

I've been playing Gen 2 and 3 lately, and I'm wondering if they're gonna be able to introduce some new staples to the game that'll compare to Gen 2 just a bit. Will we finally get a Steel Eeveelution, a new type, and something else to change things up?
